got some parts in from China, but I need to test them to see if they actually work. they've been painted and remarked (of course 😑)

the ADC was tricky to test. one of them was bad and had some stuck outputs.

I wonder if it'll work? I'll have to fire up the Apple II to find out.

@tubetime I like the “Apple II goes here” silkscreen.

@tubetime "Apple II goes here" ok, now I know you made it... I can guess its a super-rare IIe card that nobody has seen the likes of since the day after it came out...

@tubetime :-) Amazing. Before buying are you able to simulate the board, and is that useful?

@benjohn there aren't any models of the larger chips. it's easier to just make the board and try it out irl!
