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

Disassembling ROM #0 reveals an initialization routine that checks for a hardware dongle marked 'ORION-ENC-84'.
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.

Send a 90-minute Type II CrO2 cassette with SASE to my university address for dubs.
