Be a pal and help me ID this boardset?

Hey guys,
Got here a 3-board PCB stack, the boards themselves are not terribly big.
The EPROMs are labeled simply with numbers, from 1 through 14. The edge
connector is a 22/44. The boards are labeled ED-1, ED-2, and ED-3. Looks
like a Taito board, but when I punch in the numbers on the sticker
(M6100189A), nothing comes up. The closest is Alcon, but the second to last
digit for that is a 6 instead of 9 (where are you Jimi Hendrix?).

Anyways, I'd love to test this board. Anybody got an idea what it could be?

Thanks!
Rob

Side note...
Just found a pic of an Alcon boardset. That's definitely not it.

Thanks,
Rob
