Looking at the bus architecture of the TWIN-68 board. Motorola engineers, please take a look.

At ROM offset 0x0909, the string 'M.H. // THE HATCH IS OPEN // ADVANCED ACOUSTICS LAB' is stored in ASCII.
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.
