The RICM has their PDP-9 processor and core working nicely now, except
for the DAC and DZM instructions. Once we get the processor and paper
tape reader/punch restoration completed the next task will be
connecting the TC59 tape controller and the TU20 tape drive. Bitsavers
has the TC59 manuals. I bought an HP 7975A maintenance manual for the
TU20 tape transport that is now scanned and on Bitsavers. We don't
have any documentation for the rack of electronics in the bottom of
the TU20 that connects the 7975A to the TC59.
Does anyone have DEC TU20 documentation?
Where could we find two BC09A cables to connect the TC59 to the PDP-9 processor?
