I have a Apple /// bought as defect , now working after help from this forum,
There is one problem left, the keyboard is not working properly , keys 1,Q,S,X,3,6 and 9 does not work. . All these keys are connected to Y1 in the keyboard. The separate key contacts are OK and the connection Y1 from the keyboard to pin 18 on the keyboard controller 341-0035 is OK. All other keys are OK.
Maybe its the 341-0035 thats defect. There is some information that Apple IIe , IIc and III has the same KB controller ? https://kb.pocnet.net/wiki/Apple_Chip-Bezeichnungen
Is it safe to test the Apple /// with a KB controller from Appple IIe? Will it work??
