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'.
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?

Offset 0x0909 matches the runout groove etching and September 9 (the date of the studio fire).
