Hi,
Me again - I was the guy having issues with my 950's ADB port/video artifacts and SCSI2SD booting/Sad Mac:
Quadra 950 board #1
The issues could be described as: (just in case y'all have any more ideas)
Quadra 950 board #2
You may have seen this board on eBay, which I got specifically to replace the #1 above board. Now I have two I can't do much with.
What the hell do I do?
(PS, I'm inserting the obligatory "looking for a Pisces PDS card and internal caddy CD bezel" but would just be thrilled if I could get it working again - I promised it the PPC PDS card from my 700 if it cooperates with me)
Thanks!

- ADB is on crack. Text carat blinks super-fast, repeats almost instantly and equally as fast. Mouse requires 4-5 super-fast clicks to register as one double-
- video artifacts with NuBus video card; on-board seems to be OK
- replacement Apple Ethernet NuBus card (SONIC model w/ 68000 CPU) is recognized in Slot A but locks the system up when I try to select it in AppleTalk cpanel
- SCSI2SD with last good SD card image (taken Feb 2018 before issues) results in 0000000F major, 00000021 minor. Gray screen with ? mark as expected if I boot without SD inserted, but panics after I insert so maybe a bad disk driver (Lido, FWB, etc - I can't remember which one)?
- I booted from a physical HDD I used to have on my 700 before replacing it with a SCSI2SD.
- file copies, Snooper logic board tests, etc are super slow with ADB keyswitch set to ON. I left it overnight for a repeating test (including basic RAM 101010) and this morning the RAM test was only 10% or so done. Should have taken a couple of minutes. I took out everything but 128 MB RAM bought earlier this year from MemoryX.
Quadra 950 board #2
- Purchased on eBay two weeks ago - owner stated it was a working pull from a 950 with a damaged side panel in 2002, sealed in a bag ever since.
- Doesn't chime, even with no RAM installed, it should at least boot chime and death chime? No video, SCSI drive light blinks as I would expect would happen, part of the usual POST process
- I swapped out 68040s with my other 950.
- No obvious trace damage. Yesterday was the first opportunity to work with it. The "upper right" corner is cracked (i.e., the corner on the end by slot $E) but I checked and don't see any traces that would have been broken on either site. (just green space
