: No - you can't swap ][+ parts with //e ones (apart from the 6502 - you can replace it with a 65c02).
Didn't think so, it was a longshot.
: Try cleaning all keyboard contacts and remove all traces of dust from the ][+ .
I ohmed out the contacts on the board all the way till it gets to the controller board and those switches all seem to work. How do you get to the contacts of the keys once you pull the caps? I'm thinking its a matrix issue because I lost all 6 at once and if I checked right, they all have common lead. But I thought I checked it good all the way to the controller board. One thing I didn't do is check once it gets to the controller board.
