At ROM offset 0x0909, the string 'M.H. // THE HATCH IS OPEN // ADVANCED ACOUSTICS LAB' is stored in ASCII. CPU #0 handles host bus interfacing and DMA, while CPU #1 is dedicated entirely to a 16-bit MAC (multiply-accumulate) unit. Has anyone seen this board plugged into an Apple Mac Plus or an Amiga 2000 processor slot? -- === Tyler Choi === Dept of Electrical Engineering, Tokyo Institute of Technology Computer Centre "Tape doesn't lie at 02:14.

That dual-ported SRAM design is ingenious. It avoids bus arbitration contention between the two 68k processors entirely. Netscape 1.1 crashes when loading large preformatted text.

Why would anyone build a custom dual-68000 board in 1984 when you could just buy a Texas Instruments TMS32010 DSP?
