MOS8_030

Nice! Thanks, that's good information for the forum to have.

Yes, exactly.

Playing around with my card and thinking about this more, I think this particular card only supports 4mb, regardless of 32 bit support. The instruction manual provided by Bolle is for a later model Quick30 board. Wish I could a find the specific manual for this card.

Wet sand the resin copy with some 1000 grit sand paper then move up to 1200 and eventually 2000.

Maybe here? https://www.newertech.com/tech_support/support_legacy.php

If it's 117mhz upgrade then it's probably a Newertech card and would certainly require Newertech software to properly enable.

You're using a 68K '030 install on an '040 PB with a PPC upgrade card. I'm not surprised there are issues. I'm sure there are at least PB/040/PPC enablers/extensions that are missing. I would just do a clean install on the PB.

Can you send a copy of that to Apple and have them forward it the iTunes team?

No, I do not. I was going by the information on everymac's page. I've worked on many, many G4 systems but I was usually only interested in OS9 if I was working on the Classic side. If I ever ran across a G4 with 8.6 I probably upgraded the OS to 9.

Uninorth refers to the chip that passes data between the processor and the memory. Uninorth was what Apple called the chip. In a PC this chip is usually referred to as Northbridge. But in this context it refers to the early grey G4 Macs. Most of them are capable of running 8.6. This page has the specs for the G4 Macs and lists the minimum OS that they will run. https://everymac.com/systems/apple/powermac_g4/index-powermac-g4.html

There are components on the mother board that can fail and cause the symptoms you are seeing, but it could also be the floppy drive. You'll have to find some way to test the floppy drive with another computer to isolate the problem. Or test another known good drive in your computer. Look online for a pdf copy of Dead Mac Scrolls by Larry Pina and Mac Classic & SE Repair and Upgrade Secrets also by Pina. They contain information about troubleshooting floppy drive issues.

You're going to have to open the system and remove the floppy drive and do the cleaning & lube procedures outlined above. There's also good chance that one of the tiny gears in the drive may need to be replaced.

Howdy! Have you tested the floppy drive from the Classic in your LCIII to confirm that the drive itself is not the problem?

Probably not your problem, but there are versions of 10.4.x that are Intel-only and PPC only, just a thought.

You should determine exactly what model you have to understand exactly what OS it will run. (Early models needs minimum 10.3.5 and the later model needs 10.4.2. They should all run 10.5.x) There are several websites that will decode the serial number and tell you the model.
