Weird cardset - any ideas?

My bad on that "FPGA". I got out my 'serious' reading glasses, looked at it more closely and it's a Z180 processor. There's a lot of connectivity on these boards, so it makes sense they could have been part of a POS system: serial lines to communicate with the terminals.
These are really well made boards, and about half the chips are socketed. -- Ian

Triad used to be very big in POS systems, particularly in the auto
parts business. Does that make any sense with your gizmo? Is that
an FPGA or just a custom gate array?
