I've had the case and panel for an IMSAI for a while and I just put together a CPU repro board from tindie. the front panel had some bad logic chips and a couple of troublesome switches, the CPU is untested since being assemble by me, and I need help understanding where I stand.
I have another S100 machine that I really haven't gotten into, so I have a few cards to use. I have inserted a Compupro RAM 17 with switch 1 set to 1-9 on, 10 off (1 is front panel control). switch 2 is currently set to 1 on, all others off.
with the RAM 17 installed, I had very limited control until I taped off pin 20 on the RAM card per some info I found here:
do I also need to tape off pin 70?
here's what it does as of now. Can anyone advise me where I stand from this?
