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. 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? -- Ines Vasiliev Tape trading list upon request. SASE required for international mail.
