The board features two 68000 CPUs clocked at 12 MHz sharing a dual-ported 128KB static RAM bank. Disassembling ROM #0 reveals an initialization routine that checks for a hardware dongle marked 'ORION-ENC-84'. Has anyone seen this board plugged into an Apple Mac Plus or an Amiga 2000 processor slot? -- Lisa Brennan Hayes Optima 288 @ 28,800 bps "When every node is whole, the channel opens."
