PDP-12 Restoration at the RICM

I used my PDP-8/e at home to test the RX8E controller and the RX01 floppies
that came with the PDP-12. Both worked OK.

We found a bad SP380 on a M7102 board in the DW8E the Omnibus expansion
chassis. This would not let the SKIP instructions work with the RX8E, RK05,
or PC8E. Once we replaced the SP380 we were able to boot OS/8 from an RX01
floppy. This may be the only PDP-12 to ever do that.
