Yes it is consistent every boot/reset.
its working all the way until it don’t one day. And I recapped and found this error. I don’t see any broken traces, how should I change the ram then? It’s soldered.
Just recently there was a thread about recreating the 6100 PDS card riser, to allow an HPV card to be installed. The OP also was interested in recreating the 68-pin VRAM sticks, as those cards use them too. However, I believe the problem was with sourcing the appropriate RAM ICs.
Thanks very much!
I've stripped out most RAM modules, still no joy, I will now try swapping a few of them around.
Does the machine need a cache chip in order to boot?
Can I use the CPU board from a 7500/100 (630-1219-A) ?
Hm, that looks like 682 to me which would be 6.8k. There seem to be a bunch on digikey. You'd just need to narrow down to the right package size.
Perhaps this one would work?
In case anyone is wondering, I wound up ordering a SCSI2SD v5.1 adapter, and using this adapter I don't observe the problem. I'm guessing it's a compatibility issue between the Classic II and the SCSI2SD v6 adapter. I'm going to reach out to the designer other SCS2SD and file a bug report, but it's not a big deal - I have plenty of other possible uses for this SCSI2SD v6 adapter.
