Usb or Firewire adaptor that would fit a 25 pin scsi cord?

I have an old Iomega 100 ZIP reader that was compatible with my G3, when my G3 died I had no way to access the zips with my new Macbook Pro, since there is no SCSI port.
Is there an USB or Firewire adaptor I can purchase that will connect to the 25 pin SCSI cord so I can hook up my Zip reader?
If there is not an adaptor, does anyone know how or where I can back up these files to cd's?
Thanks.

Welcome to Apple Discussions!
There is a device here that converts UltraSCSI to FireWire, but the ZIP 100 is not Ultra. It's an expensive gadget.
You could probably find a used external ZIP 100 USB fairly cheap. See:
http://www.amazon.com/Iomega-Zip-100-Portable-Drive/dp/B00000J3Q7
We have one and used it to move all the files we'd put on ZIPs from two old Macs with SCSI ZIP drives to our newer non-SCSI Macs.

USB to Firewire adaptors

I've seen cables advertised as USB to Firewire adaptors. Can these be used to connect USB devices to a Firewire port? One of my USB ports is dead and the other can be flaky at times.
Thanks
iBook G3 Mac OS X (10.3.9)

Hi Tar,
I'm afraid there are no such converters available that work in the required direction.
There is one I'm aware of which will run from a FW device to a USB2 ported computer, but associated software is for Windows only, as I understand it - see http://www.pixela-1.com/captycable/
It won't work in the reverse direction (which is what you would need), and, as I understand it, can only be used for connecting a video camera's FW port to a USB2 computer (by reporocessing the FW signal into video , and then sending this to the USB port) , not for other purposes such as general firewire devices like drives, burners, etc etc. So its not for you. Even to achieve only this it costs $120US.
There have been some "dual" firewire /USB hubs on the market but they all require you to have a cable to your computer's FW port and another cable to your computer's USB port to provide both forms of connection.
Your answers , I'm afraid, are to get the existing USB ports sorted out or to see if you can find FW peripherals to replace the USB ones.
Cheers

Is there usb to firewire adaptor for macbook air

I have macbook air and want to connect my lacie drive via firewire but dont have a firewire port. can you connect via a usb to firewire adaptor?

Going down such as Thunderbolt to Firewire might be an option, but best bet for that is probably going to be Apple...Thunderbolt is an Apple invention.
Sonnett makes really great products, I put one of their G4 processor cards, when you could still do that, into my PPC Mac and changed it from a 604e processor to a G4. Worked flawlessly. Their products are very likely to do exactly as advertised.
Speed of connection goes: USB, Firewire 400, Firewire 800, Thunderbolt. Unfortunately there are not very many Thunderbolt drives on the market at this point. Too new technology.

Interested in buying an old 35mm prime lens for my film camera that would fit and EF mount.

Interested in buying an old 35mm prime lens for my film camera that would fit and EF mount. I've found plenty of FD mounts and plenty of newer EF lenses around $200-300. Would like somethign in between if anyone has something. Does not have to be Canon brand.

I would not buy Canon FD or Minolta MD lenses as they will need a very expensive modification on order to work with any Canon EOS camera. (film or digital) There are cheap adapters available, but they have cheap glass optics that ruin the image quality.
Old Manual Focus lenses from Nikon, Pentax, and Olympus can use a very inexpensive adapter with Canon EOS cameras and still give great results.

Is there a Maximum amount of USB and Firewire Ports that can be added?

Can someone tell me if there is a maximum number of USB or Firewire ports
that can be added to an iMac by using hubs? I sometimes find myself running
short and wonder how this can be corrected. Also, the new iMac has
one Firewire--is there such a thing as a Firewire hub? Thanks for any info.

I think the exact numbers are:
USB. Up to 127 devices, including the hub devices, may be connected to a single host controller. iMac G4's have two controllers between the three ports (the port next to the modem has it's own controller shared with the modem(which also counts as a device)).
Firewire. 63 devices daisy-chained or though hubs one of which is the computer.
Most Firewire devices have two or more ports so you can daisy-chain the connections without a hub.

USB vs Firewire (Adaptor)

Howdy,
Does anyone know if the Firewire iPod charger charges the iPod faster than the USB charger? My instinct is no- they charge at the same rate, but I've always been lacking in the sciences.
Also, for those Firewire and USB 2 combo cables- can one plug in both the USB and Firewire cable to get an extra fast d/l to the iPod, or is it a one or the other situation?
Thanks in advance for any info.

My experience with the USB and Firewire iPod AC chargers is that they use more or less the same time to fully charge an iPod.
If you have an USB2/Firewire iPod cable, it is very important to note that you cannot plug both ends into the computer at the same time. Doing so may render your iPod unrecognizable and may have other unforseen problems as well. You can only connect one end.

Testing speed of usb and firewire cables?

I have a bunch of usb and firewire cables that I would like to test somehow to determine if they are usb 1 or 2 and firewire 1 or 2. Some cables are labeled as high speed usb, some are not and some have no labels at all.
1. Is there a way to do this in Tiger?
2. For transfering data to an external drive, is Firewire 400 or usb 2 faster?
Thanks!

Hello kat.hayes,
Let's take your three questions in the same order:
Question #1: Technically, No, USB cables have the same termination ends. However, not all cables are made to the same standards and quality (shielding has a lot to do with how well they work/last). Quality cables are at a minimum double shielded but that does not stop mfg's from making claims about "high-speed". If there is a problem with the cable, you will know it in that the device connected will not work. Period.
The 2nd part of your question #1 regarding "bottleneck" is that if the USB2 port receives the slower USB protocol from a connected device, it will negotiate to the lower speed. Not a "bottleneck" exactly, as the external device you have connected will determine the speed. Not the USB cable.
I don't know why you are trying to figure out the speed of the USB cables.
It really comes down to what you want to do with your computer and what type of external device you need to connect. If you have a choice of which type of device to use, choose FW(See below #2 for a brief explaination).
Question #2: The issues and technical debate about which protocol is better(faster) really are meaningless as the final speed determinate is controlled by the chip/interperter that the manufacturer of your external device choose to use. If the device uses inferior chipset design, then no amount of "maximum rated transfer speed" for either FW or the USB-2 is going to make a bit of difference.
FW is usually faster. It comes down to the protocol used by the two designs. The one major diffence that benefits Firewire users is that it is isosynchronus. That means that if you have for example 3 devices, that all 3 would get 400mbps bandwidth to use, while USB2 is shared between devices. This is the ugly side of using USB2. If you a want an in depth technical explaination let me know.
Regarding your question #3:
Your Power Mac G5 has one FireWire 400 port on the front (rectangular shape with one pointed end), one FireWire 400 port on the back, a FireWire 800 port on the back(square,blocky shape), and four USB 2.0 ports—one on the front and three on the back. There are also two USB 1.1 ports on the keyboard. See this link:
http://manuals.info.apple.com/en/PowerMacG5Late2005_TechBrief.pdf
If thats not clear, here is a card showing two FW800 ports (square) and one FW 400 port (rectangular w/pointed one end).
http://www.1394store.com/eshop/product.asp?dept%5Fid=42&pf%5Fid=1225
Technically, FW400 is refered to as 1394a and FW800 as 1394b.
So, plug any USB2 into the computer only. USB1 devices can be plugged into either the computer or the keyboard.
And FW400 & FW 800 into the correct, differently shaped recepticals.
If you let us know what you intend to do with your external devices and I'm sure there will be a number of excellent suggestions, hopefully based on personal experience, on which protocol would best fit your situation.
Hope this helps.

Daisy Chain USB To FireWire?

Hi all.
I'm not really sure where to post this, so any suggestions about a better place would be great. Anyway, here's my question.
I do a lot of work with photos, and they take up a lot of hard drive space, so what I'm planning to do is this: I'll buy a big external hard drive with lots of connections (1 USB, 2 FireWire 800, 1 FireWire 400). I'll also buy a smaller external hard drive with much less in the way of connections (1 USB only). The big drive will act as my main storage drive, with all the files for each image included on it. The smaller drive will act as the bakcup drive, with the top 20% or so of my best photos in only a compressed format on it. I want the smaller (backup) drive to be as cheap as possible, as I don't have much of a budget at all. Here are the two drive selections I've made: big drive:
LaCie Big Disk Extreme+ Triple
Small drive:
WD Elements
Desktop
So, here's the question: I know that you can daisy chain FireWire drives that have more than one port together, like this:
A cable from FireWire port on Drive A to FireWire port on Drive B, then a cable from another FireWire port on Drive B to the FireWire port on computer. I know this works (right?).
But I don't want to have to spend more money on Drive A (the backup drive) so that it has a FireWire port. Since Drive B (the main drive) has a USB port, I thought I would run a USB cable from Drive A to Drive B like this:
*Setup 1*:A cable from the USB port on Drive A to the USB port on Drive B, then a cable from the FireWire 400 port on Drive B to the FireWire 400 port on the computer.
Will setup 2 work? Will the data from Drive A make the crossover from USB to FireWire? If not, I suppose I could also use this setup:
*Setup 2:* A cable from the USB port on Drive A to one of the FireWire 800 ports on Drive B, then a cable from the FireWire 400 port on Drive B to the FireWire 400 port on my computer. Will this work better? Do USB to FireWire 800 adapters really work?
So, basically, all I really need to know is whether or not Setup 1 will work, and if it doesn't, whether or not Setup 2 will. Also, if anyone has any info/reviews/stories about the two drives I've selected, I'd love to hear that as well.
Thanks so much in advance for any help I get. Sorry about the long post; I hope it made sense.
Thanks again.
Nate

Thanks for the response!
What about Setup 2, though? Does someone sell a USB to FireWire Converter?
Nobody has heard of a USB to FireWire converter that works.
The first example you gave would require a USB B to USB B cable or perhaps a "gender bender". Both of the drives you're looking at seem to still use the original full-sized USB B port, while many have gone to the mini-B. It wouldn't work anyways since both are USB slave devices. USB was never designed to daisy-chain.
Why can't you just connect the USB-only device to the USB port. If you're strapped for ports, then maybe a USB hub. You wouldn't even need a powered hub if you have a few low-powered devices and this external drive which doesn't use bus power.

Bad audio quality - USB to headphones adaptor?

Hello,
I've had my MBP for nearly a year now, and have had a problem with the audio quality ever since I got it. The problem occurs when the music is quiet or there is silence - there is a lot of white noise, and occasional beeps and pops. It seems that this is a common problem with MBPs? This isn't a problem I have with any other device, and is not due to the encoding of the music (the same music library produced excellent sound on my old 12" powerbook).
I was wondering whether there exist any good quality (and small) USB adaptors for headphones? I presume this would solve the problem by bypassing the audio card altogether? If so, could anyone recommend such an adaptor that would be mac-compatible?
Thanks!

Not an answer to your question. But I got confirmation last week that this is a known issue. See my earlier thread. http://discussions.apple.com/thread.jspa?messageID=7831115
I'd be interested to know about any headphone adaptor you find. You should send the bill to Apple though.

Why can't I print a playlist of 24 songs with this newer version that will fit on a case, as I was able to do with the older version?

With the older version I was able to print a playlist of 24 songs that would fit on a case. The print was single-spaced on the older version, but on this version, the print is double spaced and it no longer fits on a case. Does anyone have an answer?

No other solution at this time. Are you using iPad or iPhone?
iPad - I can understand why you ask. It's too bad you can't sync PDF playlist. Right now the only way is to use Sugarsync. From there you can "Open PDF in iBooks". Or you can use Goodreader.
iPhone - Why would you want to use iTunes and iBooks? Although iBooks is well designed and handles PDF very well even on iPhone, it doesn't have text-reflow feature which makes PDF reading useless on iPhone unless you want to loose your eye sight soon. So the only way is to sync a folder using Sugarsync. You can access Sugarsync from Goodreader.

SCSI to USB or FireWire cable/adapter

i have an old LaCie 4GB external hard drive i'd like to get some files from, however, i need to find a solution to getting the 25-pin SCSI port adapted to either USB or FireWire so that i can use my G5 to extract the files.
anybody know of a reliable solution or product?

Start here to adapt the 25 pin scsi to 50 pin

What is the best graphics card that can fit in the hp p7-1003w?

The card that came with my CPU. the ATI Radeon HD 4200 is too weak to run the demanding games such as Arma 2, so I need a good graphics card that would fit and balance my motherboard, so the videocard and the graphics card could keep up with one another.
This question was solved.

CHHeinrich, welcome to the forum.
Before you can upgrade the video, you will have to upgrade the power supply unit (PSU). The existing PSU is only 250W. The newer mid-level video cards require a minimum of 400W to run properly. I normally recommend at least 500W. This will allow for some future upgrades. I like Corsair and OCZ PSU's. Here is a PSU that will work. I suggest measuring the existing PSU and comparing the measurements to the one that you choose.
Now, you can't use integrated video when a dedicated video card is installed. So, you don't have to worry about one keeping up with the other. I like XFX, EVGA, Sapphire and PNY in that order. Here is a video card that should give you a good performance boost. You should stay under 9" in length to assure that the card fits into the space provided. Always read the Customer Reviews on any products that you buy to see what the users have to say about them.

What is wrong with my 30" Cinema Display? The USB and FireWire ports still work, but the screen is pitch black. When you plug it into the computer, it detects that it's a Cinema Display.

When you plug it into the computer, it detects that it's a Cinema HD but the screen is pitch black.
For some reason, the USB and FireWire ports still work.

If you shine a really bright light directly into the screen can you then see a faint image on the screen? If so, that would indicate the backlight has died (hardware failure) and the unit needs repairing.

Usb or Firewire adaptor that would fit a 25 pin scsi cord?
