  1. I just love the historical bits that some of you are adding to the discussion. Really fascinating!
  2. That's correct, mine is the Apple OEM. Interesting tidbit on swapping ROMs between cards.
  3. Something interesting happened, after removing the /SystemFolder/Preferences/Display Preferences the display really slowed down. This was especially noticeable with tabbed folders. So I added "9600 Graphics Accelerator" Extension back, restarted and things are back to normal. I think I can't do much more other than try another PCI slot but I will do this only after documentation makes that claim. Thanks a million all of you! I will keep you updated with what happens when the card is in another slot.
  4. On driver concerns/mentions for the Twin Turbo 128 - According to http://oldcomputer.info/apple/Power9600/index.htm the upgrades section mentions that Mac OS 9.1 has the video driver built-in for the stock card which is the same as the one he has a photo of in the following link: http://oldcomputer.info/gallery.php?spgmGal=Museum/Apple/Power_Mac_9600_350&spgmPic=15#spgmPicture What's odd is that he mentions makes mention of a video driver which I installed but when I attempt to open it I get the following message: "A Twin Turbo PCI card can not be found in this Macintosh." Please shutdown check the installation and try again", http://web.archive.org/web/20060318204335/http://eshop.macsales.com/Tech/index.cfm?load=ixmicro.html - Drivers for IX Micro video board. In fact as the inits display as the machine starts up, this init has an X over it to indicate it is not compatible or irrelevant. At the time of writing the above I did have the "9600 Graphics Accelerator" version 4.0.6 Apple extension installed and active. This is the native driver that gets installed with the original Power Macintosh 9600 CD. I originally installed 9.1 on this machine using a 9.1 retail disc. I then used OS 9 Helper to bring the machine up to 9.2.2. From what I read the "9600 Graphics Accelerator" is not required in Mac OS 9.1 because it is built in apparently. I wonder if 9.2.2 has it built-in as well? I disabled the following and restarted to understand if there was any impact one way or another on performance. - "9600 Graphics Accelerator" Extension - Twin Turbo Acceleration v 4.0.6 (Extension) - Twin Turbo Control Panel - Twin Turbo M8 upgrade (extension) - Twin Turbo Upgrade (extension) - Twin Turbo Control Strip RESULTS: The machine's video performance remains the same. I am afraid that this card is as fast as it will ever get. NOTE: This is a caption from the Power Mac Read Me - Part 1 for disc "691-0000-A,Z,Power Macintosh 7300, 8600, and 9600 series. SSW v7.5.5. (CD) {image modified} [English International].toast", available on the internet archive. "Removing the 9600 Graphics Accelerator. When you turn on your computer, icons appear along the bottom of the screen to indicate which system software extensions are being loaded during startup. On Power Macintosh 7300, 7600, and 8600 models, this extension may appear with a red “X” through it. This “9600 Graphics Accelerator” extension file is only required for use on Power Macintosh 9600 models that contain the optional video card. If you are using a Power Macintosh other than the 9600 model, you can delete this extension file if you wish. To delete the “9600 Graphics Accelerator” extension (located in the Extensions folder inside your System Folder), drag its icon to the Trash." Some other things I've done: Trashed the /SystemFolder/Preferences/Display Preferences I apologize for the long reply, hopefully all the info, though sporadic, might help someone in the future. TO DO: Find documentation that provides evidence, one way or another, if installing the video card on a specific PCI slot yields higher performance. Thanks for your patience. Alex
  5. Hi Thanks for the reply. Currently the Power Mac 9600 has the video that card that came original for this machine. I just powered the machine on to gather the card details. According to the Apple System Profiler, the display card is in Slot B1. It's a Twin Turbo 128. The only problem I have with the card is that there appears to be a redraw of windows as I windows move from foreground to background and the like. There appears to be no different if I chose millions or 256 colors, both color depths perform the same. It would be ideal if someone with the same model as I could make a claim on performance increases using a different card. I am not running games on the machine just some utilities. I don't yet have a plan on what utility this machine will serve just yet, at the moment I am rediscovering old software and a project as it were it something I have yet to establish but at the moment, my primary goal, if possible is to speed it up slightly. I should mention that I may have come across literature mention a different slot, other than B1, to enjoy higher performance. I should investigate if there is any truth to this. With respect to hacking the PC variant of the 9200, on second thought I might not want to do that especially because of the ROM aspect, it is just too involved I think. If it meant a hardware mod, I might be more inclined. As it is, this is not a deal breaker. I do like the 9600. Maybe I should find meaningful purpose for it other than just installing software. I am in that experimental stage yet. Would love to hear any further thoughts you or anyone else might have.
  6. Hello forum members I am enjoying my 9600/300 but the stock GPU card is something of a snail. I understand the ATI Radeon 9200 is an option that I can consider. Are there any special requirements? Does the card have to be specific to Mac and if not can the hardware for a PC model be modified to work on a Mac? What about drivers? What about OS considerations, will a 9200 work with only a range of Mac OS's? What else do I need to consider. I did a Google search but perhaps my query was poor, I couldn't find anything concrete relative my questions. Kindest regards —Alex
  7. Hi, just an update, I settled with an Eizo FlexScan L768, works well but it's a tad old a slightly blurry but I think it's the age of the monitor. Then again it was VERY cheap. Earlier I said I went with a L568 but I must have typed that by mistake. Thanks!
  8. I went for this very affordable EIZO L568 in white. I like it because it also does swivel and will provide native support for the 9600 which I plan to use with much more regularity than the Quadra 950. Thanks LaPorta! There is even Mac OS 9.2.2 support, which I can't run on the Power Macintosh 9600 but it's there, https://www.eizoglobal.com/support/db/products/software/L568#tab02.
  9. Wonderful, thank you for taking the time to write back LaPorta!
  10. Hello I have a few vintage macs and there are two that I would particularly like to connect to a more modern (likely a used 10 year old) LCD. So I have about 5 different adapters on hand and that help get XGA+ or something else out of these machines. I have a Quadra 950 (built in video) with PowerPC 601 card and a Power Macintosh 9600 with the stock video card. I can already run these two macs on a Sony GDM-C520 but I want to get them on an LCD because the image might be slightly sharper and prefer to dedicate the Sony for MAME emulation. --- I don't want specific model numbers that I should buy, I just want to know what the highest native resolution these two machines output and from there I think I can find a VGA display that can accomodate these two macs at a resolution output they both share. Short update: I went to everymac.com and found more on video out resolutions On Q950 video: By default, the Macintosh Quadra 900 only supports a single display, but a second one can be supported with the addition of a compatible NuBus video card. The onboard video can support 512x384 at 24-bit and 640x480, 832x624 and 1152x870 at 8-bit. With 2 MB of VRAM installed, it can support up to 832x624 at 24-bit and 1152x870 at 8-bit. On 9600 video: *This video card supports a maximum resolution of 1600x1200 at 24-bit. It also supports 512x384, 640x480, 800x600, 1024x768, 1152x870 and 1280x1024 at 24-bit. *IX-Micro Twin Turbo 128 video card with 8 MB The other concern might be the sync refresh rate. Should I worry about this? Should I get a display with a 1152x870 native resolution then. I don't care too much about 24 bit on the Q950. Kindest regards —Alex
  11. @pcamen I did rebuild the internal battery for a powerbook 2400c only. It is not difficult to do. Unfortunately it did nothing for the powerbook 2400c, it remains in GLOD mode.

    SCSI to IDE adapters (bridges)

    I suppose that economic circumstances kind of suggest scsi 50 to 68 pin adapters and a 68 pin SCSI drive.

    Thank you for the post, appreciations deserved!

    SCSI to IDE adapters (bridges)

    So the main issue here is that these are not manufactured any more, or so it seems. I sent an email off to Acard with what my goal is, a 50 pin to IDE bridge/adapter. We'll see what they say but as you pointed out, these adapters today are incredibly expensive.
  15. Hello As everyone knows SCSI hard drives are becoming scarce and there are SCSI to memory cards but how about SCSI to IDE. I think this would be a pretty good solution. Has anyone installed one of these on their vintage scsi only macs? The first one I found on using google shows that these are not cheap. Any good source to consider, any where in EU or N.AM would be good.
