Just Googling around, it looks like it was possible to flash the ROM on a Mac, but the historical repositories for those ROMs (and some instructions) are mostly dead. I do have a Rage 128 that's working fine for now, and is probably more than adequate for my needs. It would be great to double...
Man, here's hoping System 7 Today is never taken down. Good to hear of someone who's used those drivers successfully in System 7. My 7000 is very similar, but has S-Video instead of composite and a different label on the heat sink. I've tried it in a 6500 and the 8600 with the same result. I...
You're right, I think that narrows it down to the MB or the ROM. The DIMM chips work.
Quite a PCI roster there. One other reason I installed 8.6 was to see if the Radeon 7000 64mb I have would finally produce an image — no dice. I don't think my model plays well with Classic. What model...
All slots still report 64MB with the stock 604ev. Back to the Crescendo 700.
In the meantime, swallowed my fondness for System 7 and upgraded to 8.6. The machine now boots reliably and doesn't bomb every time I try to do something interesting!
Very interesting, @jeremywork. My 8600/300 has a Sonnet Crescendo installed, but I do have the original CPU. I will pop that in and see if I get a different reading.
I did try a few sticks in some random slots. All reported 64MB.
The Hardware Developer Note states:
"The method of RAM expansion in the new models is essentially the same as in their earlier counterparts: 168-pin, 8-byte DIMMs as defined in the JEDEC MO-161 specification."
Possible these...
Eight large chips per side.
The chips labeled C1-C16 (side A) and C17-C32 (side B) are marked:
SAMSUNG or SEC KOREA, followed by a number that varies, 943, 937, 946, 925, 112, 040, 943
KM48C8000CS-6 or K4F660811D-TC60 or others.

Thanks for the tip on RAMometer. It also reports 512MB instead of 1GB (passes the test, FWIW). I might find an OS 9 CD and see if I get a different reading in there.
I just put in eight 128MB sticks of RAM into my PM 8600, but System Profiler reports that they're all 64MB sticks. All slots are reporting. This is on System 7.6.1. The sticks are clearly marked 128MB. Is this common, do I have mislabeled RAM, or could it be a System 7 issue?
I've heard of High Sierra breaking other apps. This one could be a casualty as well. Since the error is related to the Host application, I would check the path to it in the app package to make sure it's not different in High Sierra.
