Hardware teardown of the dual-68000 DSP accelerator board used in the Stardust project.

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?

The MAC unit looks like a precursor to the DSP56001 that Motorola put in the NeXT and Atari Falcon.
