Question Regarding iMac G4

Quick question that I know a lot of you may know.
I have an opportunity to pick up an iMac G4 800mHz that someone is giving away. The issue with it is the logic board is kaput. Do I have to replace it with another 800 mhz logic board? Or would it be "upgradeable"? Just kinda wondering...Thanks so much guys.

The 1GHz and 1.25GHz Logic boards have different ports (both internal and external) so you'd have to put another 800MHz board in there. They are expensive more than a Mac Mini once you include fitting and the lack of USB2 and Audio-In make the 700-800MHz machines of limited interest. 
You can upgrade a good logic board to 1.35GHz but again the cost is prohibitive..

  • Hi, I want to downgrade from OSX LEOPARD to OSX TIGER but I have a few questions regarding this. My iMac is originally from 2007 it came preloaded with tiger. I have original install tiger discs version 10.4.10. Is it safe to downgrade or not please help

    Hi, I want to downgrade from OSX LEOPARD to OSX TIGER but I have a few questions regarding this. My iMac is originally from Sep 2007 it came preloaded with tiger. I have original install (2) tiger discs version 10.4.10.  I want to know if it is safe and what are the necessary steps to do so. Also by downgrading im wondering if a lot of apps nowadays support tiger for example I have photoshop version 5 and 4 these are very important to me. One last question does anyone know of any reliable virus protection for mac that doesnt slow down your computer? because I have read that a lot of them do so. If anyone can help me I would greatly appreciate it! Here are the specs for my iMac 
    Model Name:
    iMac
      Model Identifier:
    iMac7,1
      Processor Name:
    Intel Core 2 Duo
      Processor Speed:
    2 GHz
      Number Of Processors:
    1
      Total Number Of Cores:

    Most of the time a perception of general slow performance is the result of installing third party junk alleged to speed up, "clean" or "optimize" your Mac, or to look for viruses that don't exist. Ideally you would know what you installed so you can uninstall it, but if you don't know or aren't sure there are techniques such as Safe Mode and creating a temporary user account to confirm that suspicion.
    If you open Activity Monitor it may show a process, or processes, that occupy a lot of your system's time.
    Slowness confined solely to web browser activity is often the result of an inexorable progress toward websites that demand ever more processor-intensive tasks. If your slow performance is strictly limited to web browsing, you might try disabling Flash by either uninstalling it, or use utilities such as ClickToFlash that allow you to control what Flash content gets loaded. Flash in itself is not inherently evil, but there is nothing to stop websites or the advertisers who pay for them from writing horrible Flash code that can do everything from hogging 100% of your CPU's time to causing random crashes. You can watch Activity Monitor as in the above to correlate these troublesome web pages with performance degradation.
    You are correct; if your computer shipped with Tiger you may certainly revert to it. I forgot that Tiger was shipping on new Macs as recently as five years ago. To downgrade it would be necessary to completely erase your hard disk and boot with the Tiger installation DVD, followed by installing it anew. Such drastic measures are not necessary and you are unlikely to be satisfied with the results anyway.
    Assuming your system is free of third party parasitic junk attached to OS X in an ill-conceived attempt to improve upon it, that your hard disk drive is sound and the boot volume has enough free space to work with, by far the best performance-enhancing improvement would be to add more memory. Buy as much as your computer can use and that you can afford. 2 GB is not that much any more.

  • Question regarding mic plugged into audio in/optical digital audio in port

    So I have this external headset... headphone/mic set combo... I plug the headphone jack in the headphone slot and the mic jack in the audio in/optical digital audio in port slot in the back of my IMAC. I go to my system preferences select "sound" and "line in - Audio line in port". But when recording, it's still recording from the internal mic? How do I just record just from the external mic??? What am I doing wrong? I've read all the other questions regarding how to get the external mics to work, but it's still recording from the internal mic? Help?
      Mac OS X (10.4.9)  

    I never expected APPLE wouldn't make a mac that didn't have a proper mic jack?
    It has a proper one, a good one, a professional one, not the toy that comes with most PCs. Apple has used line level analog audio input for years.
    From Wikipedia;Line level is a term used to denote the strength of an audio signal used to transmit analog sound information between audio components such as CD and DVD players, TVs, audio amplifiers, and mixing consoles.
    In contrast to line level, there are weaker audio signals, such as those from microphones and instrument pickups, and stronger signals, such as those used to drive headphones and loudspeakers. The strength of the various signals does not necessarily correlate with the output voltage of a device; it also depends on the source's output impedance, or the amount of current available to drive different loads.

  • Several questions regarding File Vault

    Hi!
    I have several questions regarding File Vault - right now I'm using Mac OS 10.4.8
    1.: The battery lock of my iBook is defect thus it happens from time to time that while transporting it the battery drops out while the laptop is sleeping. What happens with the File Vault-disk image?
    2.: I want to (have to ) set up my Intel iMac again. The installer-CD I have will bring it back to 10.4.6
    AFAIK the data format used for File Vault since 10.4.7 is version 2. What happens if I encrypt my stuff now (10.4.8 - thus version 2), back it up to my backup disc, install a new system (10.4.6 - therefore version 1) and want to access my data via Migration Manager (don't want to use archive and install)?
    3.: How do I actually do a backup of my data while the system is running? The backup should be encrypted as well.
    I use the demo-version of SuperDuper for backing up my system because with it I can ensure that I have a complete bootable backup of my running system.
    Thanks for your answers in advance
    ibook g4 12" 1.2 GHz 768 MB RAM / Intel iMac Core 2 Duo 17" 2.0 GHz 2GB RAM   Mac OS X (10.4.8)  

    Parker,
    You said:1. If it did, Apple would not use FileVault, as everyones computer will have a battery problem once in their life, and Apple would lose buisness from angry people who lost all of their data.I have seen enough reports of data loss with FileVault that I feel compelled to dispute your statement.
    In Data corruption and loss: causes and avoidance, Dr. Smoke writes...If your data-security needs demand FileVault, you should backup your encrypted Home folder regularly, preferably daily. Like any hard drive or disk image, a Home folder protected by FileVault — an encrypted, sparse disk image — does not respond well to the causes of data corruption...Loss of power definitely is a cause of data corruption.
    For Niels....,
    An Unencrypted Look at FileVault, by François Joseph de Kermadec is an excellent discussion of the features, pitfalls, and cautions regarding Filevault.
    Although the article discusses Panther and is dated 12/19/2003, the concepts as they apply Tiger have not changed.
    The cautions and warnings are prominent in any of the Apple Knowledge Base articles referring to the use of FileVault. If a user is unfamiliar with any aspect of FileVault, it should not in my opinion be activated.
    As good as FileVault is in protecting your sensitive data, it also presents the danger of locking up your files in an irretrievable ball of one's and zero's. Backups are critical. You must ensure that you have a comprehensive backup plan. Backup and Recovery, by Dr. Smoke is a fine example of what you need to consider.

  • Wiget question regarding system usage

    I'm a recent convert from the PC world and am finding the dashboard feature very useful. I did, however have a question regarding the way wigets in the dashboard access the iMac's system resources.
    Specifically, I was wondering if a wiget is installed and appears in the "Manage Wigets" list but is NOT active on the dashboard, does that wiget still utilize the system's resources? (i.e. is it still actively updating its information or performing its task) Or does it "sleep" until you actively enable it in the dashboard?

    Welcome to Discussions!
    I believe widgets don't consume resources unless you have them open in Dashboard-just having them installed, but not open wouldn't consume resources.

  • Question Regarding MIDI and Sample Accuracy

    Hi,
    I have 2 questions regarding MIDI.
    1. MIDI is moved by ticks. In the arrange window however, you can move a region by samples. When doing this, you can move within values of the ticks (which you can see on your position box that pops up) Now, will this MIDI note actually be played back at that specific sample point, or will it round the event to the closest tick? (example, if I have a MIDI note directly on 1.1.1.1, and I move the REGION in the arrange... will that MIDI note now fall on the sample that I have moved the region to, or will it be rounded to the closest tick?)
    2. When making a midi template from an audio region, will the MIDI information land exactly on the sample of the transient, or will it be rounded to the closest tick?
    I've looked through the manual, and couldn't find any specific answer to these questions.
    Thanks!
    Message was edited by: Matthew Usnick

    Ok, I've done some experimenting, and here are my results.
    I believe those numbers ARE samples. I came to this conclusion by counting (for some reason it starts on 11) and cutting a region to be 33 samples long (so, minus 11, is 22 actual samples). I then went to the Audio Bin window, and chose to view region length as samples. And there it said it: 22 samples. So, you can in fact move MIDI regions by samples!
    Second, I wanted to see if the MIDI notes in the region itself would be quantized to the nearest tick. I cut a piece of audio, so it had a 1 sample attack (zoomed in asa far as I could in the sample editor, selected the smallest portion, and faded in, and made the start point, the region start position). I saved the region as a new audio file, and loaded it up in the exs sampler.
    I then made a MIDI region, with and triggered the sample on beat 1 (quantized, on the money). I then went into the arrange window, made a fixed cycle length, and bounced the audio. I then moved the MIDI region by one sample to the right. I did this 22 times (which is the number of samples in a tick, at 120, apparently). After bouncing all of these (cycle position remained fixed, only the MIDI region was moving) I imported all the audio into the arrange on new tracks, and YES!!! The sample start was cascaded by a sample each time!
    SO.
    Not only can you move MIDI regions by sample, but the positions are NOT quantized to Logics ticks!
    This is very good news, and glad I worked this out!
    (if anyone thinks this sounds wrong, please correct me, but I'm pretty sure I proved it, in my test)

  • Question regarding homehub and Open reach router -...

    Hi all,
      I had infinity installed earlier this month and am happy with it so far. I do have a few questions regarding the service and hardware though.
      I run both my BT openreach router and BT Home hub from the same power socket. The problem is, if I turn the plug on so both the Homehub and Openreach Router start up at the same time, the home hub will never get an Internet connection from the router. To solve this I have to turn the BT home hub on first and leave it for a minute, then start the router up and it all works fine. I'm just curious if this is the norm or do I have some faulty hardware?
      Secondly, I appreciate the estimated speed BT quote isn't always accurate, I was quoted 49mbits down but received 38mbits down - Which I was happy with. Recently though it has dropped to 30. I am worried this might continue to drop over time. and as of present I am 20mbits down on the estimate . For the record 30mbits is actually fine and probably more than I would ever need. If I could boost it some how though I would be interested to hear from you.
    Thanks, .

    Just a clarification: the two boxes are the HomeHub (router, black) and the modem (white).  The HomeHub has its own power switch, the modem doesn't.
    There is something wrong if the HomeHub needs to be turned on before the modem.  As others have said, in general best to leave the modem on all the time.  You should be able to connect them up in any order, or together.  (For example, I recently tripped the mains cutout, and when I restored power the modem and HomeHub went on together and everything was ok).
    Check if the router can connect/disconnect from the broadband using the web interface.  Leaving the modem and HomeHub on all the time, go to http://192.168.1.254/ on a browser on a connected computer, and see whether the Connect/Disconnect button works.

  • Question regarding IWDTree and context Value Node naming

    Hi,
    I have a question regarding the IWDTree / IWDTreeNodeType components.
    I have a context looking like this:
    Context
      + ResponseNode
        + PersonNode (1..1)
          + PersonAddressNode                    (empty node, placeholder)
          | + AdresNode (0..n)
          + PersonChildNode                      (empty node, placeholder)
          | + PersonNode (0..n)
          |   + PersonAddressNode                (empty node, placeholder)
          |     + AddressNode (0..n)
          + PersonParentsNode                    (empty node, placeholder)
            + PersonNode (0..n)
              + PersonAddressNode                (empty node, placeholder)
                + AddressNode (0..n)
    The context represents a person, a person's address, and a person's children and parents with their respective addresses.
    As a result, on different branches, a PersonNode and AddressNode can appear.
    And for some strange reason, all PersonNodes and AddressNodes link to the same ResponseNode.PersonNode.PersonParentsNode.PersonNode and ResponseNode.PersonNode.PersonParentsNode.PersonNode.PersonAddressNode.AddressNode respectively, irregardless of their branch...
    Is it illegal to have multiple PersonNode and AddressNode node names, and should they be named uniquely?

    Generally, node names need to be unique inside the context, attributes in different nodes can have same names. I wonder if the context structure you described will result in code without compile errors.
    The WD Tree can only be used with recursive context nodes or with a hierarchy of non-singleton child nodes.
    Can you give an example how your tree should look like at runtime?

  • Question regarding roaming and data usage

    I am currently out of my main country of service, and as such I have a question regarding roaming and data usage.
    I am told that the airplane mode is sufficient from keeping the phone off from roaming, but does this apply to any background data usage for applications and such?
    If the phone is in airplane mode, are all use of the phone including wifi and application use through the wifi outside of all extra charges from roaming?

    Ann154 wrote:
    If you are getting charged to use the wifi, then it is possible.  Otherwise no
    Just to elaborate here, Ann154 is referring to access charges for wifi, which is nothing to do with Verizon, so if you are using it in a plane, hotel, an internet cafe etc that charges for Wifi rather than being free .   Verizon does not charge you (or indeed know about!) wifi usage, or any other usage that is not on their cellular network (such as using a foreign SIM for example in global phones)  So these charges, if any, will not show up on the verizon bill app.  Having it in airplane mode prevents all cellular data traffic so you should be fine

  • Question regarding MM and FI integration

    Hi Experts
    I have a question regarding MM and FI integration
    Is the transaction Key in OMJJ is same as OBYC transaction key?
    If yes, then why canu2019t I see transaction Key BSX in Movement type 101?
    Thanks

    No, they are not the same.  The movement type transaction (OMJJ) links the account key and account modifier to a specific movement types.  Transaction code (OBYC) contains the account assignments for all material document postings, whether they are movement type dependent or not.  Account key BSX is not movement type dependent.  Instead, BSX is dependent on the valuation class of the material, so it won't show in OMJJ.
    thanks,

  • **question regarding 3G and wif**.

    I have a question regarding 3G and wifi. I have #G activated as well as wifi, when I go to retrieve mail for example I get a pop up asking me if I want to connect to a wifi network…should I have wifi and 3G activated at the same time, and why am I getting the pop up…
    Thanks

    You can have them on at the same time, but they will not be used at the same time for data. The order of preference for data is WiFi > 3G > EDGE > GPRS. You're getting the pop up, most likely, because you have Settings > Wi-Fi > Ask to Join Networks set to ON. You can set that to OFF, and the iPhone will still join known (i.e. previously used) WiFi networks automatically.

  • Question regarding Dashboard and column prompt

    My question regarding Dashboard and column prompt:
    1) Dashboard prompt usually work with only for columns which are in subject area. In my report I've created some of the columns which are based on other columns. Like I've daysNumber column that is based on two other columns, as it calculates the difference of two dates. When I create dashboard prompt I can't find this column there. I need to make a prompt on this column.
    2)For one of the column I've only two values 1 and 0. When I create prompt for this column, is it possible that in drop down list It shows 'Yes' for 1 and 'No' for 0 and still filter the request??

    Hi Toony,...
    I think there was another way of doing this...
    In the dashboard prompt go to Show option > select SQL Results from dropdown.
    There you need to write your Logical SQL like...
    SELECT CASE WHEN 1=0 THEN PERIODS.YEAR ELSE difference of date functionality END FROM SubjectAreaName
    Here.. Periods.Year is the column which is already exists in repository's presentation layer..
    and difference of date functionality is the code or formula of column which you want to show in drop-down...
    Also write the CASE WHEN 1=0 THEN PERIODS.YEAR ELSE difference of date functionality END code in fx of that prompt.
    I think it helps you in doing this..
    Just check and inform me if it works...
    Thanks & Regards

  • Questions regarding customisation/configuration of PS CS4

    Hello
    I have accumulated a list of questions regarding customising certain things in Photoshop. I don't know if these things are doable and if so, how.
    Can I make it so that the list of blending options for a layer is by default collapsed when you first apply any options?
    Can I make it possible to move the canvas even though I'm not zoomed in enough to only have parts of it visible on my screen?
    Is it possible to enable a canvas rotate shortcut, similar to the way you can Alt+RightClick to quickly change brush size?
    Is it possible to lock button positions? Sometimes I accidentally drag them around when I meant to click.
    Is it possible to lock panel sizes? For example, if I have the Navigator and the Layers panels vertically in the same group, can I lock the height of the navigator so that I don't have to re-adjust it all the time? Many panels have a minimum height so I guess what I am asking for is if it's possible to set a maximum height as well.
    Is it possible to disable Photoshop from automatically appending "copy" at the end of layer/folder names when I duplicate them?
    These are things I'd really like to change to my liking as they are problems I run into on a daily basis.
    I hope someone can provide some nice solutions

    2.  No.  It's a sore spot that got some forum time when Photoshop CS4 was first released, then again with CS5.  It's said that the rules change slightly when using full-screen mode, though I personally haven't tried it.
    3.  Not sure, since I haven't tried it.  However, you may want to explore the Edit - Keyboard Shortcuts... menu, if you haven't already.
    4.  What buttons are you talking about?  Those you are creating in your document?  If so, choose the layer you want to lock in the LAYERS panel, then look at the little buttons just above the listing of the layers:
    5.  There are many, many options for positioning and sizing panels.  Most start with making a panel visible, then dragging it somewhere by its little tab.  One of the important features is that you can save your preferred layout as a named workspace.  Choose the Window - Workspace - New Workspace... to create a new named workspace (or to update one you've already created).  The name of that menu is a little confusing.  Once you have created your workspace, if something gets out of place, choose Window - Workspace - Reset YourNamedWorkspace to bring it back to what was saved.
    You'll find that panels like to "stick together", which helps with arranging them outside of the Photoshop main window.
    As an example, I use two monitors, and this is my preferred layout:
    6.  No, it's not possible to affect the layer names Photoshop generates, as far as I know.  I have gotten in the habit of immediately naming them per their usage, so that I don't confuse myself (something that's getting easier and easier to do...).
    Hope this helps!

  • Question regarding ONT connection via Ethernet and Cable cards

    Hi,
    We recently upgraded to Fios Quation 150Mbps/65  plan. We are not getting the advertised speeds (we only get like 5mbps upload) so verizon is sending a tech to switch the ONT connection from coax to ethernet.
    I have 2 questions regarding this new setup:
    1. If the ONT communicates with the Fios Actiontect router via ethernet instead of coax from now on, How will the set top boxes and Tivo-esque cable card powered device I currently have connected to coax, talk to the verizon system from now on, if coax is taken out of the equation? Will fios signal still flow through the internal coax wiring of the house? And moreover, I was under the impression that coax was the way set top boxes communicated and derived independent ip addresses from the Fios router, for on deman purposes and what not. How will this work from now on?
    Quiestion 2.
    Right next to the wall where the ONT sits, theres's a basement office where we have a PC that connects to the Fios system  via an Actiontect MoCa adapter (ECB2500C) which I assume derives it internet connection from the Fios Actiontec router which sits upstairs in the living room. 
    Again, with the Coax about to be disabled next Friday in favor of ethernet connection from the ONT, I assume this PC will be left without internet because of the lack of internet signal in the coax? Is this correct? 
    Question 2.5 If my above assumption is correct, since this office is right on the other side of the wall where the ONT sits outside the house, would it be possible to run an ethernet wire through the wall that connects straight from the ONT to an ethernet switch inside the office, from which I would derive a connection for this basement PC (properly firewalled of course) and then, from said switch, continue running the ethernet wire that would ultimately reach the Actiontec Fios router upstairs from which the rest of the house derives it's internet?  and would this setup affect in any way the propper functioning of the cable boxes in the house?
    I'd appreciate your input and any help you can provide so I can have a ballpark idea of what to tell the Fios guy to do when he comes on Friday.
    Cheers.
    Solved!
    Go to Solution.

    It's not valid to have two devices connected to the ONT, PC and VZ Router.  Must be a single device. The ONT locks onto the MAC Address of the first device it sees. Since you have TV you should have the VZ router as the internet facing router.
    Other options:
    1.  Have the VZ Router located next to the PC in the basement and then use Wireless for all other PC's.
    2.  Have the VZ Router located next to the PC in the basement but run one wire upstairs and connect a switch where other PCs and devices can connect via a wire.
    Hope that helps.
