Күн бұрынTook me months to sort out. Should of looked at a circuit diagram in the first place. IC17 was the problem. Came up with 4 when I did a POKE 0 and PEEK. I must of damaged the pads taking the old chips out.

I was pointing at the wrong chips in the video. IC15 is 1, IC16 is 2, IC17 is 4, IC18 is 8, IC19 is 16, IC 20 is 32, IC 21 is 64, IC22 is 128.
