Quadra 950 Various Crashes

Still running strong so far...

Still doing ok. Hopefully stays that way.

Argh.. image corrupted again. I've about exhausted the easy debugging... only thing easy left to try is a non emulated SCSI (ie. real disk).

If that doesn't help, I'd have to start attempting repros while watching various signals, and not sure I have time or the patience for that.

Actually, should probably try changing out the voltage regulators...

i guess when i use a bluescsi v2 on the high/fast speed setting in a 950, i have to use the berg power. otherwise it's unstable

Yeah, my ZuluSCSIs always are powered via the floppy/berg connector. Didn't help me

I got a working spinning disk from @techstep so when I get a chance, will test with a real drive to see if my issues are caused by the scsi emulation device.

Have you tapped right off of main power from the power supply? like the 5v rail going into the motherboard? Or used a external power supply? Have you already tried? Not meaning to say retrace, just double check.

What do you mean by tapped? The power for the ZuluSCSI is coming off the 5V accessory connector on the power supply and last time I measured it was healthy.
