Does anyone recognize this?

It looks like some kind of 8-bit computer or at least a trainer but I can't find any information about it:

I think that it's a simple digital logic trainer. You have a 555 clock circuit, a lot of small breadboard areas by each IC, some switches and some LEDs. I don't think that it's any more than that. Use Google image search for "logic trainer" to see lots of similar stuff.

The three ICs on their own are simple octal buffers. This looks to be part of something...

After figuring out how to get a magnified image, it's pretty clear that this is a breakout board for an MCU (signal labels silk-screened by the big connector pretty much cinch that. Matches up with the pinouts given here

I have no idea how you found this PDF! Very impressive. Do you also know which MCU? I see "MCU CARD H1" in that PDF but I can't find a chip named that.

I think it's the 68HC11 MCU--that pairing of PA1/IC2, PA2/IC1, PA0/IC3... is pretty distinctive. Here's the datasheet
