Mac Plus

After about fifteen minutes using my old macintosh plus, the screen goes black. The computer still runs while this is happening, and the screen flickers back on when I tap the side. Is it a fire hazard and can I fix whatever is wrong myself? Thanks

A bad solder joint would probably be one thing to suspect. Using electrical equipment under such circumstances is not safe. Please note that all work inside a compact Mac is very dangerous due to the high voltages involved, and must be carried out by an expert only. High-voltage charges may be present for a long time after the computer has been switched off.

  • How to create 800K disks for Mac Plus

    I've acquired a Mac Plus in good working condition, but it's just standalone. Eventually I want to network it, but for right now, is there a way to use my Mac Mini or a PC to create 800k disks for the Mac Plus? Things like OS upgrades and other software are available out on the net, but I can't get them to the Plus. I've tried a USB floppy disk drive on the Mini, but it only works with HD diskettes.

    sacsr,
    "Can I take MacPlus-appropriate software from the internet, burn it on a CD on my Mac Mini, and load it into the Mac Plus?
    Yes! : ) That simple. The Plus was the first 'business Mac' and I loved it until I got a dual floppy SE with an external SCSI HD and an excellerator card with a math co-processor. It was a very capable computer. But, as soon as you used a faster Mac, you never went back to the Plus. You could fix lunch while waiting for disk swapping to boot and load MS Word 3.
    What we are saying is that the SCSI bus on the Mac Plus has far more options available for someone shopping for resources.
    We have over 300 Macs of almost every model. We have been given over 100 floppy drives. We shop at government surplus stores and auctions. In all that stuff, we only have a couple of 800 k drives but hundreds of SCSI devices. They are SO much easier to find and are so much cheaper to buy and customize.
    If you can find a Macintosh 800K (M131) floppy drive, great. Then you also have the problem of finding double density floppy disks ( high density disks with tape over the hole are not reliable in the older drives.)
    here is a website with the whole list:
    http://www.mandrake.demon.co.uk/Apple/drives.html
    I remember buying an 800k floppy drive new in 1986 for several hundred Dollars. The external CD-ROM drives sold for $300.
    It will probably be much easier to find an Apple 300 or 600i CD-ROM drive that should read CDs burned in your modern Mac. Your original question was about floppies. The real question is "How do I get data from a new computer to an old computer." That question offers more possibilities. I am suggesting a better and cheaper alternative. Having fun with older equipment requires purchasing intermediate equipment.

  • Mac Plus software needed

    I have an original 128K Mac that has been upgraded to a 1MB Mac Plus that is being readied for sale. Unfortunately, somewhere in this mess I have managed to lose the OS boot floppy. I have the complete set of System 7 install diskettes, but the proFile they had been loaded on went south. Anybody happen to have this disk?
    Also open to offers if anyone is interested in buying. This includes the Mac soft case, extended keyboard, mouse, case cracker tool and long-shaft torx, internal vent fan, and the back case with the signatures of all the folks who worked on the original Mac, including that of Steve Jobs.
    Thanks.

    You have two other options open to you:  Apple still offers disk images of Mac OS 6.0.x for download, though you need a way to move .sea files from the internet all the way down to a Mac capable of writing a 800k disk, no mean feat for sure.  That downloads page is here:
    http://support.apple.com/kb/TA48312#system
    There is also someone selling ready-made disks from these images:

  • Modem 300 compatibility with Mac Plus

    I have an Apple Modem 300 that I use with my Apple //c.  It connects to the Internet (in some ways) just fine.  I have a Mac Plus 4MB and I was wondering if the Modem 300 specifically could be compatible with the modem.  If so, also please tell me how I can.  I already have Netscape installed on my Mac Plus.

    For the cable connection, the following article could perhaps be of interest.
    http://support.apple.com/kb/TA33629
    However, the modem speed is extremely low. It would of course be much better to use a faster modem (something like 14400 bps). Almost any PC-style (DB-25F port) modem can be used with a Macintosh Plus through a Mac modem cable (DB-25M to MiniDIN-8M).
    I did not know that it was possible to use a Netscape web browser on a Macintosh Plus (with an external hard drive) computer. There are a few alternatives that work, such as MacWeb (under System 7). An old version of Eudora can (if SMTP authentication is not required) be used for email. You would also need MacTCP and an appropriate PPP program. For details, see the web pages below.

  • Mac Plus show no video

    hey.
    I just got a Mac plus from a friend. He says it worked when he put it into storage 8 years ago. When I got it home, I tried to put it up. It sounds like it works (get boot chime, will start to read the attached scsi drive, etc) but it shows no video. I have tapped the side, top, everything. I even have it sitting upside down. How do I get it working again?

    There is only one way to properly repair your Macintosh Plus. Before you start, you ideally need a PDF copy of Apple's official service manual for the Macintosh Plus, which can be obtained if you know where to look. A copy of Larry Pina's Macintosh Repair & Upgrade Secrets is also essential, in my opinion, because it is the only book to this day to detail the correct diagnostic and repair procedures for compact Macintoshes. Used copies of this book can be purchased from Amazon and other retailers online.
    You will need to open the case, and you will need a T15 long torx screwdriver to do this. Once the cover is removed, you must discharge the CRT before you proceed any further. By searching on Google you can find sufficient guides on how to properly discharge a CRT. Unlike the SE and later compact Macs, the flyback transformer in the Plus does NOT have a built-in bleeder, which means most of the charge is still there after you power down. The CRT in a compact Mac holds about 9,000 volts. Avoid touching the anode cap, video board, CRT neck and yoke, and the analog board. In the Macintosh Plus, the power supply is exposed on the analog board. This also contains high voltage which is dangerous.
    Another way to get rid of most of the charge initially is to turn the brightness to full while the machine is ON, and then flip the power switch at the back to the OFF position. This is a quick and relatively safe way of getting rid of most the charge. Do this, then let it sit for a week, then discharge using the correct procedure. Then you should be safe to proceed to the next stage.
    According to Larry Pina's book, no video usually means that you need to resolder the pins on the J4 connector. If this is not the problem, you may need to replace U2 and/or replace the LAG chip on logic board.
    In addition to what the book states, I highly recommend capacitor replacement. The capacitors most likely need replacing on your analog board. Capacitor failure is common in machines of this age. Electrolytic capacitors lose capacitance as they age, and can sometimes leak. Replacement components are easy to source and soldering new caps is easy, providing you have at least basic soldering experience. Inspect your analog board carefully for dry solder joints. Also check for golden-colored joints.
    If you have a copy of Pina's book, it has component lists in the Appendix for the analog board. If you cannot find a copy of it, I can scan and upload the pages you require to repair your Plus.
    Hope this helps, let me know how you get on.

  • Mac Plus System 6?

    Does anyone know where I can find a floppy with System 6 on it so I can run my Mac Plus again? I don't know what happened to my system disks. When I boot with my System 6.08 tools disk it doesn't work. I'd love to play Loderunner again.

    You can find System 6.0.3 through 6.0.8 on 800k floppies, as well as 1.44 MB floppies for 6.0.8 here:

  • Mac plus operating system?

    Hello everyone,
    I just pulled my old mac plus out from my garage, and was wondering where i could get a operating system floppy disk so i could use it, because when i turn it on it either:
    Has a black screen and beeps continuously.
    Or just has a blank white screen that flashes on and off every few minutes...
    i would appreciate it if anyone could tell me anything that would help.
    thanks.

    Callum,
    Yes, any Macintosh computer with a built-in floppy drive is OK. However, for practical reasons, one of the models with a floppy drive for 1.44 MB (see the technical specifications) should be used. This 1.44 MB Mac floppy drive will handle 800K, too.
    If the Mac operating system on that intermediary computer contains a PC Exchange control panel, a PC-formatted floppy disk can be read (it will appear on the Desktop with a "PC" floppy icon). If so, just drag-copy any downloaded .bin files (as they are, do not alter them on the PC) to a PC diskette (1.44 MB), and use that floppy for the transfer.
    Alternatively, use a PC utility for Mac disks (such as TransMac or an old freeware program called HFVExplorer) for transfers on Mac-formatted 1.44 MB floppy disks.
    Once on the intermediate Mac, decode the files (use StuffIt Expander for Macintosh for this). If you do not have StuffIt Expander, you can download the MACDISK.EXE file here onto a PC. Then prepare an empty PC-formatted 1.44 MB diskette via FORMAT A: in DOS or the full formatting option under Windows. Launch the MACDISK.EXE program on the PC. Follow the on-screen directions. This will result in a floppy with a StuffIt Expander installer that can be used in a Macintosh computer.
    One additional difficulty is that you need 2DD/DSDD diskettes for the final step where 800K floppies are created in Disk Copy 4.2. 2DD/DSDD disks have only one square hole (with a slider), whereas a "normal" 1.44 MB HD diskette has two (one with and one without a slider). 2DD/DSDD diskettes are hard to find today. The magnetic materials are not the same, but for a very temporary use (expect errors) one can cover the extra square hole (the one without a write-protect slider) in an HD diskette with a piece of tape.

  • Mac plus - system 6 images

    hey guys,
    i recently picked up a mac plus and have downloaded the system 6 images from the support section.  unfortunately, when i use stuffit to try and expand the images, it tells me that "the stuffit engine was unable to determine the format"
    any suggestions?

    Please note that the Macintosh Plus cannot use 1.44 MB (HD) floppies. 800K (on DSDD/2DD diskettes) is the maximum size.
    External USB floppy drives are not capable of handling the special 800K Mac format. Instead, a pre-1998 Macintosh computer with a built-in floppy drive will have to be used in order to create working 800K floppy disks from downloaded disk images.
    The files at the Apple download site are encoded MacBinary (.bin). Usually, it is a good idea to keep this encoding unaltered until on the computer where the system disks are to be made. Once there, an appropriate version of StuffIt Expander can be used to decode the .bin.

  • Mac Plus CD-ROM question

    Hi,
    my Mac Plus has an external (of course ^_^) SCSI CD-ROM device, model M2850G. I want to use to transfer some document from my PC. But, I was able to read some old CD-ROM created on PC, but not all, expecially the more recent CDs I've burnt on my PC with Windows utilities.
    I don't know if it's caused by CD-R modern supports, or by some not-compatible configuration on my PC burning program (NERO).
    On my PC, I have Windows XP Pro SP3, and Nero Burning program version 9.0.9.4.
    My Mac Plus has a 6.0.x OS system with CD-ROM extensions.
    Thanks in advance for help.

    Usually an older CD drive won't read a disk because the burn speed was too high. Your old Apple CD rom is probably a 2X or maybe 4X. You should be able to set a lower burn speed on your PC preferable 2X but my guess is 4X might be the slowest depending on your PC's drive.

  • Mac Plus keyboard cable

    For a Mac Plus keyboard cable, can I substitute a phone cable or is the Mac jack wiring specialized?

    Hi,
    >Is everyone agreed that phone cable needs modification?
    If I place the two plugs of a Macintosh Plus keyboard cable next to each other (side by side) on a table, both pointing in the same direction, with both tabs up, the wires are arranged as follows:
    yellow-green-red-black  yellow-green-red-black
    Placing the two plugs of a handset cable from one Swedish telephone the same way, results in the following:
    yellow-green-red-black  black-red-green-yellow
    Both cables use the same type of plug (4P4C).
    As shown by this simple comparison, at least these two cables are different.
    See also the 'Data port' text in this article:
    http://en.wikipedia.org/wiki/4P4C#4P4C
    In the case of the Swedish telephone handset cable above, it appears as if turning one of the two plugs 180 degrees (using a crimping tool) would result in a cable that could be used for a keyboard. However, this is not a recommendation. Proceed at your own  risk if you decide to carry on with any experimental modifications. I have not tested any modified cables.
    You should check whether randomly chosen telephone handset cables in your country have the same wiring/colours as the one I examined.
    Jim may also want to verify the wiring and colours with another Macintosh Plus keyboard cable.

  • Buddy, can you spare a mouse for a Mac Plus?

    Well, I've tried to make the topic as descriptive as possible. I've got a Mac Plus and need to get an old document from its innards, but I have lost the mouse. Does anyone know where I can find one for sale in the UK, so that I can get my hands on it as soon as possible? Or maybe maybe maybe someone can lend me one for a day?
    Thanks very much for your advice and assistance.
    Best wishes to all, George

    Jim-
    there is a reference to the HD20 on that site, here:
    http://www.vintagemacworld.com/hd20.html
    but alas, no pictures.
    Based on the torturous Startup sequence described in that article, I don't think George has an HD20.
    >"It is my understanding that such hard drives are configured to work with a Mac Plus alone; their configuration is such that their contents couldn't be accessed by a more recent Mac."The Mac Plus required that you use a special format that put the next-numbered sector staggered every third sector around the disk. If you did not, the Plus was so slow it would miss the next-numbered sector if they were sequentially numbered, and still miss if they were every-other. The drive would have to endure an entire revolution of the disk to read the next sector.
    If you missed the data at 3600 RPM = 60 spins/sec, or .016+ seconds, or 16.7 milliseconds additional per sector.
    But the point is that that format is compatible and can be read just fine by SCSI-equipped Macs.

  • Trials w/ Mini Vmac emulating Mac Plus to play Sid Meier's Pirates

    I was up for swashbuckling on the high seas & bought the classic game, Pirates, from Ebay. Using Mini Vmac, I've got the emulator running & then did a crash & burn when getting Pirates to start. The Mini Vmac site seems spotty regarding directions for adding software, like games to the Mac Plus desk top emulation. I may need to make the game into a ROM file for the Mac Plus to see Pirates, but don't know how.
    I tried opening original apple software Disk Copy 4.2 to make a disk image for the emulator but the vmac didn't recognize the file and wanted to initialize it, maybe because Disk Copy 4.2.sea had an extension that Stuffit expander 11 didn't convert to a usable file b/4 making the disk image. SetFType.dimg couldn't make a mountable file either.
    Glad to have the mini vmac emulator working, but I'm not on the high seas yet, any suggestions?

  • 4-MB Mac Plus and AppleCD 300i Plus

    Can anyone help me with this dilemma? I am trying to (if possible at all) to hook up an either internal or external CD-ROM (AppleCD300i Plus or 300e) so I can upgrade my system from 6.08 to 7.5.3. I have an external 40 mb SCSI hard drive that is currently booting up to System 6.08.
    I just bought a System 7.5.3 CD from E-bay and I want to be able to hook up either an internal (is this possible on mac plus?) or external CD-ROM to boot up from CD and either re-format the 40 mb hard drive with the System 7.5.3.
    I have never used the Mac Plus before as I am/was a WIndows guy and this Mac Plus gizmo I bought off flea market for $10 is really fascinating. I want to maximaize this with any help I can get from here. Thanks in advance.

    Grant has already covered the important aspects. If I may add a few comments.
    I order for me to access the CD-Rom, I need to install this "CD-ROM" driver on my exisitng SCSI hard drive?
    Yes, or onto a bootable floppy.
    To do so, am I to understand that I need somehow to download the driver first and then trasport it onto a 800k floppy, then install this ONTO / INTO the existing SCSI hard drive which currently is populated (co-exist) with System v 6.0.8?
    Yes. System 6.0.8 is a good and fast operating system for the Macintosh Plus, but it is more difficult to find the appropriate driver software (and the installation per se may be slightly more complicated than with the System 7 variants).
    I was hoping to completely re-format the hard drive with fresh install from the System 7.5.3 CD-ROM I purchased from E-Bay. Is this not possible?
    Since we do not know exactly which CD it is (model specific?) it is hard to answer that. But you could, as Grant also said, use a Disk Tools floppy and the Apple HD SC Setup utility on it. However, at this stage (when the bootable hard disk is the only bootable disk at hand) it does not hurt to wait a little. Anyway, the Disk Tools floppy will have to be produced first, and that is a problem. You can not do this on a PC, since a built-in PC floppy drive is unable to handle the 800K Mac format, not even with special software for Mac disks. The same is true for external USB floppy drives, whether connected to a modern Mac or to a PC. The only way to create an 800K Disk Tools floppy is on an older Mac (look for a model with a floppy drive for both 800K and 1.44 MB).
    If a completely fresh install to a System 7.5.3 is impossible, what recourse do I have in terms of upgrading the System from 6.0.8 to 7.5.3?
    You could erase the hard disk, once a Disk Tools floppy is available, and then install System 7.5.3, This can be done from the CD (if a bootable floppy can be modified to hold a suitable CD-ROM driver) or from the nineteen files download (each file is too large for an 800K floppy and must thus be segmented or carried over via cable). As mentioned earlier, modifications et cetera require access to another Mac.
    Does a version little bit earlier, like, 7.0.1 or something come with a CD-ROM driver extension on a "bootable" floppy (800k)so that I can first boot up with such floppy and then initiate reformat from the CD-ROM.
    Not ready made with CD-ROM software. The System 7.0.1 disks at the Apple site are 1.44 MB. There are System 7 disks in the 800K format (in some language versions), but if I remember correctly, the Disk Tools floppy has a system file which is basically System 6. Any Disk Tools floppy will have to be modified. We will certainly find one way or another to create/modify a floppy, as soon as you have access to another Mac.
    Also, I only have access to PC based machine connected to the internet. If I do download into my PC based system, is there a way to trasport such file onto a floppy disk on a PC system?
    Due to the aforementioned absolute inability to handle the 800K Mac format, a PC is far from ideal in this very case. I would suggest that you look for another inexpensive (and functional) Mac from the period approx. 1991 to 1997 (perhaps an older PowerBook), e.g. through an online auction site.
    A question in this context, though: Do you have a terminal emulator with file transfer capabilities for Mac on the hard disk (or possibly on 800K Mac floppies)? This could be a separate program or the communications section of e.g. ClarisWorks (I do not remember whether Microsoft Works for Macintosh contained a corresponding part). That would make transfers from other computers (including PCs) possible, or at least easier.

  • OS 7 boot CD for Mac Plus?

    Hello and greetings from Switzerland.
    Before getting to topics let me introduce myself a bit. I'm a private collector of old NeXT, Atari and Apple hardware, living in Switzerland and as long as being no native speaker I hope You can understand my English...
    I do have a problem that I can not solve and I'm looking for clues regarding my Macintosh Plus.
    This nice littele machine ran Mac OS 7.5.5 off an old Rodime HD for nearly three years as a webserver using MacHTTP. Now this Rodime HD has gone to see its maker and I'm facing the fact, that old drives that can be used by the plus are harder to find than other hardware I already found.
    Before I once installed a OS 7.5.5 off that harddisk onto a Iomega Zip and the Plus started off that one, too, but he does NOT start form a installed minimum os 7.5.5, which was placed onto a Zip by my PowerBook 145b. So I think any OS has to be installed off the Plus in order to run.
    As it is getting harder to find 800k floppies, too, I thought about creating a bootable OS 7.5.5 CD for the Plus. I just tested this ability by placing an old PowerBook 1400c installation CD into the 600i CD ROM and the Plus started up to the point, where he stated that this CD can not be used by the Plus - the resources for the Plus were missing because this CD is solely for the PowerBook 1400c. I expected this but the Plus booted of that CD in the beginning so it seems to be a problem that can be solved.
    As long as Apple's disk images of OS 7.5.3 and 7.5.5 only provide a installation but not a bootable system folder I began to wonder if it is possible to create a minimum bootable system CD for the Plus in order to install a 7.5.x off that CD onto a Zip connected to the Plus. I'm missing a "universal" OS 7.5.x installation CD, the only on I own is that PowerBook 1400c one.
    So does any one have an idea or clue? I would like to rely on Zip cartridges as long as those are cheap and still available, old harddisks would be even better but in both cases I need a bootable system for the Plus NOT placed on a floppy - these can get broken easily and are harder to find day by day.
    Thanks in advance!
    J
    P.S.: just in case someone is interested in and does not bother about the fact that my homepage is written in German solely You are welcome to have a look at http://www.blackmac.ch . There I'm introducing some of my old hardware and more is to come

    Hello J,
    I just got myself an old Apple 40 MB hard disk
    That is probably a very good idea. The earlier problems with booting could have been related to the Zip (either a driver incompatible with the Macintosh Plus, or a compatible driver that had been corrupted or exchanged when used on a more modern Mac; or possibly the formatting). Remember that an old hard drive used with a Plus may have to be formatted in a special way, with an interleave factor 3:1. This is usually automatically accomplished by formatting the drive when connected to the Plus. One can also, in some cases (a hidden feature in Apple HD SC Setup) set the interleave factor manually, which allows formatting at another Macintosh computer.
    and install a 7.5 onto it
    The earlier booting issue may also have been linked to a system folder that was not properly active. One can "bless" the system folder by double-clicking on the System file; or by moving the System file and possibly the Finder out of the System Folder, closing the windows, then move the file(s) back in. I guess that you with the new hard drive will be able to install a working operating system, even when creating a system folder from one of the universal options ("for all Macs") on another Mac.
    But I still would like to build a bootable CD for the Plus.
    Sorry, I am not an expert in this field. There are two web pages (here and here) at the Low End Mac site dealing with similar subjects. Could details there be of interest to you? And, as always, read the software licence agreement(s) carefully in order to stay legal.
    Alternatively, you could decide not to make the CD bootable. With a bootable disk (a floppy or the hard disk) containing the appropriate CD-ROM extension(s), the CD and its contents (no need for a system folder there then) would still be visible.
    Disk Copy 6.3.3 is available for download from Apple (German version, US version).

  • How to network to older mac plus DSL via ethernet hub?

    I just got DSL (yeah, probably the last guy on the planet who still had dialup). Anyway, I've been using ethernet to connect my old G3 to my iMac, and had to unplug it to hookup the DSL. I have a five-port ethernet hub that I used for a short time years ago to network my G3 to an even older mac. Can I use this to connect the G3, iMac and DSL? I don't really remember anything about how to use the hub. Can someone give me a little guidance please?

    You can't use a hub. A hub is an unintelligent system; it repeats all signals it gets down all its ports. This means that if you are connected to the Internet on one port, it will repeat everything on your local network out over the Internet. I'm fairly sure you don't want that.
    In addition, a hub does not do NAT, DHCP, or DNS. Basically, it does not assign IP addresses. If you attach devices to a hub, then either they must have fixed IP addresses of their own or something else must assign IPs to them. If you assign your machines fixed IPs in a private network range, because the hub is not a router and does not do NAT (Network Address Translation) and because private networks are just that, private, your machines will not be able to connect to the Internet... but because this is a hub, anything on your network will still go out over the Internet anyway. You won't be able to see the Internet, but anyone on the Internet who wants to and knows how will be able to see you. If you assign your machines fixed IPs in a network range which is not a private network, your network will be visible over the Internet and you will be able to connect... except that you'll be using a visible network range, which probably belongs to someone else, who will object, and when your ISP finds out (which they will in a very short time when the owner of the network range you're using complains to them) you may find that you no longer have an account. Hijacking someone else's network range is a ToS offense for most services. If you don't assign fixed IPs, and rely on DHCP to assign IPs, you will have multiple IPs on your network, all of which are visible over the Internet with no protection whatsoever... and, more important, you're only paying for one IP. Your ISP will be upset. Liberating multiple IPs without paying for them is also a ToS offense.
    Connecting via a hub is a very bad idea.
    You should get a router. Most home routers have a switch, not a hub, built into them. A router sits between two networks, one your local network, and one the Internet. The router has two IP addresses, one on the Internet (which you're paying your ISP for) and one on your local network (which the ISP doesn't care about). Most home routers can be set to run DHCP (Dynamic Host Configuration Protocol) on the internal network, and set up a network using one of the private ranges. As they are private, they are not routed over the Internet, and whatever you do on the private net stays on the private net, unless you specifically request an Internet connection by running a web browser or an email client or something else that goes out over the Internet. The router will then do NAT for you and send the signal over the Internet, and when it gets a reply, will route it back to your machine. Because the router includes a switch, it will send the reply directly to the machine in question, because a switch is an intelligent device and keeps a list of the machines on the local network and sends the proper signals to the proper machines. (Note that a wireless system is a hub, it broadcasts the signals to everyone in range; there's a reason why I use a wired connection for my systems...) The Internet only sees one IP, that of the router. You can have multiple machines behind the router and neither your ISP nor the rest of the Internet will care.
    I have my system set up in the following way:
    1 DSL modem talking to the Internet (set in bridge mode, so it's effectively transparent)
    2 router talking to the DSL modem (set in NAT and DHCP modes; it controls the network)
    3 multiple devices, including an external switch, connected to the router. All are configured to use a private Class C network.
