To test the hardware Computer Automation has a diagnostic tool QCD.
it is provided on 2 paper tapes.
The manual for QCD.
My system has one 8Kx16 core memory board, if i understand the manual correct it should be possible to load both part 1 and 2 of the QCD, but it don’t work for me, so i first load tape one, when it is completed, set the X register to 316 and A register to 0 and then run autoload again with tape 2.
if the load completes correct the cpu should halt and the I register should be 0800.
