    Xerox 820-II 16/8 troubleshooting

    I have a Xerox 820-II 16/8 that came to me non running. The previous owner says he had a working monitor, but it stopped displaying at one point. I have the terminal unit with a flat German keyboard and the attached ROM revision. The Unit powers up its CRT tube and emits a beep that is also...

    Wanted: NCR System Technical Manual - MS-DOS (for Decision Mate V / DMV)

    Xerox 820-II floppy cable wanted

    Hi all, I have a Xerox 820-II, but just the main part, no drives. I need to have a look inside to check if the disk controller's actually there, (at least there's a connector at the rear of the monitor), but in the meantime I'd like to research what it takes to connect drives to the Xerox. I...

    Thorn EMI Liberator

    Hi folks, I'm looking for help to disassemble the Liberator. I've taken out the screws from the bottom plate, but it's either held by plastic tabs or more screws under the keyboard. Any hints? I'd love to dump the ROM contents and take pictures for the MAME folks. Robert

    Looking for BASF 7120 / Digi-Log Microterm II boot disks

    I have this huge behemoth of a computer, but I have no software for it and there is no or only little info available on the machine. From what I've gathered, the BASF 7120 is a badge engineered Digi-Log Microterm II, a Z80 machine with another Z80 for floppy I/O. There was a CP/M for it, but...

    Hi, I just have Portable III that's pining ... not for the fjords, but for a working power supply. I dumped its ROMs, and it's now a proud part of MAME's emulated machines. Anyway, I contacted a guy with a Portable 386 if he would kindly contribute to this cause, but we're getting 101-ROM errors...

The reason I'm posting here is that I've had a pleasant email exchange with...
