MikiPERU Posted August 1, 2023 Share Posted August 1, 2023 Hello Friends, I bought an apple IIc without cables or a source, I cleaned it thoroughly, checked the circuits, used a lot of isopropyl alcohol, I have investigated and I was able to enable a 12v and 1A source with its 7-pin connector; then i saw that it is used with composite video and i have hooked it up and i have a colored squares image. I have disassembled the keyboard, fully cleaned, and checked the contacts, all OK. The disk drive does nothing. Have any of you had the same problem? What suggestion can you give me? Thank you.

MikiPERU Posted August 1, 2023 Author Share Posted August 1, 2023 I have also connected it through the 15-pin connector and it looks the same.

ColecoGamer Posted August 26, 2023 Share Posted August 26, 2023 Looks like a processor and/or video chip problem. Could also be faulty RAM.
