IIc with checkboard

Posted by: ironborn65 on 2024-10-24 08:41:00 I got this very nice Apple IIc, finally! I was looking forward for the whole set!! The pic was taken by the owner, so it's not in my "cave" yet. About the checkboard ... what should I expect? Anything already known? I searched for "checkboard" in this forum but got nothing

Posted by: stepleton on 2024-10-24 10:52:01 Try searching the web (not jut here) for "checkerboard" instead of "checkboard" --- this seems to turn up some discussion threads that might help.

Posted by: ironborn65 on 2024-11-04 09:37:07 The baby is with me now. I haven’t opened it yet, as I’m already working on the SE/30 project. The CRT is functioning, but I’m wondering—should I service it by inspecting and, if necessary, replacing the capacitors?

Posted by: bibilit on 2024-11-04 12:13:03 The CRT is small and tight , not easy to work inside. The only thing that can go wrong is the RIFA capacitor, so i will not worry until the board is not working properly.
