Does anyone know anything about these 387SX SBC's, I own two of them that I bought off eBay for $10 a piece a few years ago , I really bought them to take the 4mb 30pin SIMMs , but I was recently digging through the crap in my closet and rediscovered them and I am looking into possibly making builds with them, do they work in a standard PCIMIG backplane or do they require something special?
They seem like they could make a fairly nice and fast little 387sx box since they have a 40mhz 387sx and it looks like it should support a full 16mbs of ram , they appear to have been manufactured towards the end of 95 or early 96, there are date codes ranging from the 26th week of 95 to the 48th week of 95 on the ICs. They have a 387 co-processor socket, although I don't know what software can run well on a 386sx that would benefit from it. AN IDE channel is provided, a floppy controller is provided, there are 2 serial ports on the back of the card, It has a PS/2 keyboard connector along side the serial ports, there is a header on the board for a parallel connector, so I wouldn't need an I/O card. I would have to dig out my ISA video card video card, and I would need to pull a sound card out of one of my ISA systems to get sound, although it looks like a header is provided to connect a system speaker so I could at least get some basic sound from that.
