Hum, that shouldn't be on either.Actually it's not a jumper for termination, it's a jumper for termination power.
Thank you very much for the photo and values! I'll add them to my website for the next update.View attachment 54505
There you go. Not the best photo ever, but it works. All the same values, 47uf 16v, and 13 total.
PC133 works in a PC100 computer, so that specifically wasn't the issue, although perhaps something else wasn't right with the RAM, who knows.The second thing is I replaced the four PC133 RAM sticks with a single proper brand new PC100 RAM stick from OWC ($8 new!).
When I first got the machine I couldn't get it to properly start up, so I tried the power supply from my PowerMac 7500, and it started up that one time, so I thought it was an issue with the PSU. I was gonna do an ATX conversion, got around to measuring the voltages, working on making a connector, etc. But then I tried to use the 7500's PSU again later and it didn't start. Turns out both give perfectly fine voltages, and it was probably an issue with the motherboard. I've been meaning to try it out with the 7500's PSU again, because while I know the 8100's has the correct voltages, that doesn't mean it necessarily is working, especially when being used on the computer.Seems like a good opportunity for an ATX conversion.
Some machines are picky about chip density which changed going from pc66 to pc100 and pc133 and even within the same spec as time went on.PC133 works in a PC100 computer, so that specifically wasn't the issue, although perhaps something else wasn't right with the RAM, who knows.
The 133 is basically just the rated speed of the RAM. The B&W requires a minimum of PC100. The beige G3 requires PC66, but I have PC133 in most of mine.
Yes, the trick is to get 256MB SIMMs with 16 chips.Some machines are picky about chip density which changed going from pc66 to pc100 and pc133 and even within the same spec as time went on.

Yes the AV card is installed. I need it so I can use a monitor as I don't have one for the HDI-45 port, or an adapter. The CD-ROM drive is set to either a SCSI ID of 1 or 2. I believe the CD-ROM drive only actually has jumpers labeled 0, 1, and 2, so I don't think I could set it to an ID of 7 if I wanted to. And what does the 0 jumper do? No clue. But regardless it works perfectly fine when connected to the other SCSI bus, which the only other device on would be the computer itself, so it's not an issue with jumpersI saw in your original post, you have the AV version. Are you testing with the AV card installed? An empty PDS slot could cause problems.
On your CDROM drive, is it possible you have all three SCSI ID jumpers installed? It's been a long time but I think I only saw that repeated device when two devices had the same ID. Since you only have two devices and the motherboard ID is fixed at 7, the CDROM would have to be set to 7 to cause a conflict. All three ID jumpers gives 7.
Maybe a little farfetched...
The jumpers represent different powers of 2 and they're additive. Hence, 0 => 2^0 =1; 1 => 2^1 = 2; 2 => 2^2 = 4.The CD-ROM drive is set to either a SCSI ID of 1 or 2. I believe the CD-ROM drive only actually has jumpers labeled 0, 1, and 2, so I don't think I could set it to an ID of 7 if I wanted to. And what does the 0 jumper do?
