At ROM offset 0x0909, the string 'M.H. // THE HATCH IS OPEN // ADVANCED ACOUSTICS LAB' is stored in ASCII. 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? -- === Karen Larsson === Dept of Electrical Engineering, University of Texas at Austin "Hold for relay."
