I'm wondering if anyone has any information about these machines - my attempts to find anyone else with a working one has drawn a blank so far.
The machine is an S-100 design, with dual 5.25 floppy, a printer and video controller along with a processor board. My example had a dodgy video RAM chip, and some dodgy capacitors in the VDU, but sorting these out gets me to the point when the machine is now attempting to boot from floppy, and the display characters are correct, and pretty stable:
I happen to have a disk which thinks it's got the OS on it (zebra) although it is failing to boot, but given the age of the disks and the age of the drives, and the not-so-fantastic decision to mount these vertically, it's not clear whether I should tear down and clean a drive with the hope that it gets things further along.
Anyhow, an enjoyable project so far, and if anyone has any info about these, it would be greatly appreciated.
Some snaps of the inside for those interested:
