Hello everyone,
I’ve recovered a Macintosh IISi in good condition except for the PSU which had a significant capacitor leakage. The electrolyte was practically in the motherboard PSU connector.
Naturally, I removed all the caps, thoroughly cleaned the remaining electrolyte and re-capped the PSU. I’ve also re-capped the Logic Board.
Now the computer starts but the video output signal is strange with a wobble in the background. I’m using an OSSC with a standard DA-15 to VGA adapter but I’m struggling to determine if this issue stems from the OSSC or the Macintosh. (Of course, I only have the OSSC to test and my other old monitor doesn’t support RGB.)
Here’s a link to the video of the effect. If anyone has an idea I’d be very grateful.
Thanks for reading and sorry if I make any English mistakes; it’s not my native language.
