Pentagon 48 или GRM1 начало INTа

[Shockwav3]

Yeah, one pixel is fine for me for the moment I think inverting (part of) a signal or adding a delay/pullup/pulldown might fix it, but for the moment I'm done experimenting ... I'll get back to it in a few days once I finalize my INT + Mem + AY (+ Covox? [+ Kempston?]) interface.

@solegstar: I'll get back to that as it's currently just a prototyping circuit. On my intended addon card (currently it's a bunch of loose wires and breadboard) I still have a few gates for spare (1x LS02, 2x LS32, 1x Flip-Flop from LS74)


EDIT: Adding 2.2nF against ground on the output of the inverter for !WRFE fixed things ... seems kinda finicky (changing between 74/74LS/74ALS [155/555/1533] chip families still breaks things - currently I'm going with a 155LA3) but works well enough for me.
