Managed to dump the 27256 EPROMs from the TWIN-68 Rev C board recovered from Ashford Poly.

CPU #0 handles host bus interfacing and DMA, while CPU #1 is dedicated entirely to a 16-bit MAC (multiply-accumulate) unit.
The board features two 68000 CPUs clocked at 12 MHz sharing a dual-ported 128KB static RAM bank.

Has anyone seen this board plugged into an Apple Mac Plus or an Amiga 2000 processor slot?

Looks like a prototype telecommunications board for military secure voice, not an audio music product.

If you are posting from AOL, please read RFC 1036 before posting again.
