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? -- Mike Kim Tape trading list upon request. SASE required for international mail.
