Correction.. I meant to say 74LS08P.. The ISA card is finished now, by the way! ^^
- Just need a bit of time still for double-checking the wiring before trying. I'd like to avoid magic smoke, if possible. 😁

Tiny update. I installed the bare card without the SRAM and our house still stands. 😀

I hope at the D and E segments (128KiB between D0000 and EFFFF).. 😀

Quick update. There seems to be a short somewhere. Likely on the RAM board. I'll have to check.. 😐
