I have an Osborne 1 Technical manual which has info on the keyboard and some schematics, as well as a printout of the BIOS source. I'm out of town now, so I'll try to get it (at least keyboard info, as the BIOS source is many pages) to you on Monday.

Screen reads "insert disk and press Enter" or whatever, then refreshes / redraws all the time. This stops when I unplug the keyboard. I think I know which two pins connect to the Enter key, when I short those two pins same thing happens. I'm suspecting the 8877 FDC chip. Does anyone have: -- Memory (I/O) map -- Schematic (ja sure :-) -- BIOS disassembly -- tips on fixing the keyboard? <Snip> Wouter www.retro.co.za
