There are lines from the card going to the Nubus pins so it is doing something.
Considering the RAM works even when the PPC isn't being used some of that must go over the Nubus slot. I don't remember is the cache works without the PPC enabled.
I had fun running an old IBM Xserve 226 with a Nvidia Quadro PCIE card using Windows 2000 advanced server at 1080P. Hunting for the correct compatible card and drivers was fun to get that combination to work.
Anyway, I keep a bunch of ATI 9000 AGP cards around just because it makes using OS...
I kept a bunch of 16/24 port 10/100 switches for my old machines when they were being dumped as obsolete. Heck I even kept my old coax hub and some cables just in case. I also still have most of a spool of cat5 cable, connectors, and my toolkit to make cables as needed.
If you collect more...
Termination on 8 bit and 16 bit is a bit different.
8-bit termination is usually passive (just a bunch of resisters) but can be active (uses a bunch of voltage regulators). 8-bit termination works on 8 data lines plus 1 parity, 16 bit termination works on 16 data lines and 2 parity. So using an...
You can get a terminator for the DB25 port and not use the internal terminator.
USE ID 2,4,5 OR 6 for the scanner SCSI ID.
Most likely you just have terminator issues. You will need software/drivers for the film scanner (which you have).
Mine came with a Newer Technologies 68040/50 CPU upgrade, but it looks like this intel one:
You want one that will fit in between the pins of a Motorola 68040
You do have the CPU heatsink, correct? You can't run a full 68040 without a heatsink.
How did you remove the CPU? I have a black pry tool that came with a CPU upgrade and removing the Q950 CPU using it was pretty easy with no damage or broken pins.
