We found a loose faston connector on TB2-5 that connects the POWER AMP DR signal wire from the servo pre-amp to the servo power amp. Wiggling and reseating the faston seems to have fixed the servo problem. OS/8 CCL actually works now, so maybe that was a seek error that was not handled by OS/8. The serial-disk worked OK when we first powered the system on, but stopped working after several hours. Maybe the baud rate generator is not thermally stable? The OS/8 RESOURC program worked OK in the morning, but now hangs the processor with the "B" data-break light on, so something else is thermally unstable. I can punch a paper tape on the teletype and read it on the high-speed reader. I forgot to bring SSSD floppies to try. I used PIP to copy a text file to the "TV" VR14 device and it actually worked!
