I did a topic about restoring the RK05 drives
And A story about the PDP11/20
I didn't do a story on the TC11 and TU56H unfortunately. But it came don to a few broken TTL chips, two burned motor driver boards, bad capacitors in the H720 power, and the two motor capacitors were bad as well...
I still have to fix my 4KW core memory module, but at least it is complete.
But the Unibone was very helpful in the process to restore the PDP11/20 and peripherals. And it is still very helpful to fill up the memory to the max for this machine and emulate RL drives. So that is why I post it here too...
