Hi once again asking for help. I up graded from OS 8.06 to OS9 and every thing is ok BUT. Along the way I lost the G3 up date. The Computer works well but is much slower with out the G3. Any ideas where I can get a G3 up date disc or down load. Regards Norm.:sad:

A likely cause of the “lost G3” is not the operating system itself but the missing accelerator card software/driver for whatever G3 upgrade was installed (NuBus/PDS CPU cards from Sonnet, DayStar, NewerTech, etc.). was right that “G3” names a CPU family; was also on the right track about third‑party accelerator cards — many 7100s used NuBus G3 cards (for example Sonnet’s Crescendo line) that require a vendor extension/control panel to enable the G3 at boot. (bhphotovideo.com)

Practical recovery checklist (applies even if an older System Folder was discarded): confirm whether a G3 card is physically present (power off, open the case and look for a NuBus/PDS card with a heatsink or Sonnet/DayStar markings); if present, inspect the System Folder (Extensions) for vendor items such as “Sonnet Processor Upgrade” or the DayStar system extension and enable them with Extensions Manager, then restart. If those items are missing, reinstall the card’s installer/driver (many Sonnet installers added Mac OS 9 fixes in the 1.4.x series). If no installer is available, copying the vendor extension from the other working 7100’s System Folder will usually restore G3 operation. Note that NuBus G3 cards were documented to work with OS 7.x through OS 9.1, but later OS 9.x builds had limits on older NuBus machines — pick the driver/OS combination that explicitly supports NuBus Macs. (machut.net)

If the original accelerator hardware is gone, replacement NuBus G3 cards (Sonnet Crescendo and similar) turn up on the used market; check compatibility notes (some AV/video cards need an adapter/pass‑through) and vendor driver support before buying. Also observe the classic caution for 7100/8100 machines: do not operate these boards without the proper PDS video card or a PDS terminator in place. (bhphotovideo.com)

I'm not really sure what you mean. "G3" is a processor name, but as for updates, I think there's some built-in software updater in OS 9. In any case, it's normal for a later operating system to run slower than the predeccesor, because the latest and greatest operating system will most likely require more RAM and higher CPU clock speeds.

Thank you Joe for your comments. The 7100 used to run with OS8.06 system it kept on freezing so I cleaned out the old system and installed OS9. Iforgot to save the system folder which had the G3 update installed.
What I want to know is,can I obtain another G3 update and will it be ok for system 9. Hope this is enough info. Norm.

Hello,

I think he is referring to the Daystar (or comparable) accelerator card that could be installed inside of a PMac 7100.

The original 7100 was a 66 MHz PPC 601, not a G3 processor. If anything, you could have called it a G1.

The family went from 601 (the first) to a 603 (low power) and a 604 (better than 601, a G2), and then finally the G3 processor.

To use the Daystar card, you had a special extension that you needed to load.

I think I still have mine around. The question is, what is the version of your accelerator board?

Thank you all who tried to answer my question. I have now switched from the 7100 I was having trouble with and dug out the other 7100 which is a better set. The system is OS 8.06. The old one had a G3 up date which worked very well until I trashed it. So thank you any way. Norm.
