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 would suggest finding an external SCSI CDROM/CDRW/HD etc. to see if your card and cable work. For all you know that scanner could be toast.

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...

Are these the same as the ones on ebay for $20 plus shipping for 15 pcs? https://www.ebay.com/itm/112262269741

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).

Those fans probably help with the cover off but once sealed you don't have any cool air coming in or hot are going out unless you cut holes somewhere.

Could be.

I need to dig out my SE's and see what is inside these days since I forget.

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

Easiest way is to get a AGP Radeon 9000 Mac edition and use DVI and ADC if you have that monitor type.

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.

I did build that dual floppy LC 1 out of a normal floppy + HD machine. You need a real skinny HD for the SE to do dual floppy + internal HD.

Back during my adventurous days, I stuck a 68040/25 motherboard (with a cut down heatsink) into a LC3 just for fun. A dual floppy LC 1 is also an interesting OS 6.07+ machine (68020/16, 10MB RAM, LC PDS for ethernet), SCSI for external HD. Cheaper than a compact, faster, and still limited to...
