I used the memory test in the user manual to test each page in each slot in the system and it appears fine. This test is pretty basic, but considering that it had to be toggled in each time I moved the memory card to a new slot, I’m considering it good enough. I did not check multiple memory cards together, but I’ll assume that Nat and others did that back in the “old days”.

Power consumption for a fully populated memory card compared to only 1 bank (8 chips) populated is a little over 2 amps versus 1.5 amps on the 5 volt rail and a little over .5 amp versus .3 amp on -9 volt rail.

I still need to checkout I/O ports and that may take a bit, as I still have to hand wire the chassis for the 78S11 connectors used for I/O.
