Front Panel Madness

[Ttpilot]

Results can be seen at http://hawken.sdsmt.edu/367_at_A-E-G.mov. The LS367 chips seem to have fixed the A1 and D6 problem. The HLTA is still present, and DEPOSIT/DEPOSIT NEXT don't seem to be working. Also A8-A15 are lit upon reset, then go away during operations unless I set the the system to addresses in that range. Then they seem to work okay.

I should get my new LS367 chips on Wednesday. Let's hope that fixes the whole thing

FWIW, all the chips on the cpu board were from a kit someone was selling on eBay. I wonder if they got a bad batch of 8T97s. The 74LS123 instead of 74123 at IC-Q was also in that kit

I must be under some kind of curse lol. Digikey sent me my order for 74LS367s, but they filled it with 74HC4050s. Gotta wait for them to ship the correct chips

Oh man, how frustrating!
