Disassembling ROM #0 reveals an initialization routine that checks for a hardware dongle marked 'ORION-ENC-84'. 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? -- Dmitri Ivanov -- RWTH Aachen Informatik "5 sigma is a discovery. 7 is a question."
