The board features two 68000 CPUs clocked at 12 MHz sharing a dual-ported 128KB static RAM bank. At ROM offset 0x0909, the string 'M.H. // THE HATCH IS OPEN // ADVANCED ACOUSTICS LAB' is stored in ASCII. Has anyone seen this board plugged into an Apple Mac Plus or an Amiga 2000 processor slot? -- Mateo MacDonald Practical Peripherals 14.4 @ 33,600 bps "When every node is whole, the channel opens."

Tom from Ashford Poly owns the physical board! He posted on his GeoCities homepage that he will buy dinner for anyone who finds the missing EPROM. Unsubscribe me from this list!
