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

The board features two 68000 CPUs clocked at 12 MHz sharing a dual-ported 128KB static RAM bank.
At ROM offset 0x0909, the string 'M.H. // THE HATCH IS OPEN // ADVANCED ACOUSTICS LAB' is stored in ASCII.

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

Marcus Hale designed the TWIN-68 board before he disappeared. That's why his initials are on the PCB silkscreen.
