One of the boards (the one with a 6809 and a Z80) had a 56-pin slot with the bottom 6 pins plugged. Maybe that's an expansion slot. It looks like quitea bit of built-in hardware is scattered across the boards (floppy controller, sound generator, the two aforementioned coprocessors, and probably more stuff that I missed).
Hmm... The Z-80 with a 1771 disk controller. Wonder if there is a TRS-80 hiding in there as well....? Red
