I’ve replaced everything regarding the cassette portion of the vic. Caps, resistors, zeners, transistors. Still can’t get it to spin the reels. Says “Press play on tape”, and then I do, and it says it’s searching. Forever. No movement. I tested continuity all the way back as far as I could, and it’s fine. I don’t get it. Doesn’t show any power being delivered to the motor when I test voltage. Changed 6522 as well, and still no go.
Decided that yesterday was the day to recap the Vic. It wasn’t in bad shape, but the big 4700uF cap was leaking and corrosion was heading on down towards the motherboard. That’s just not cool.
Here’s the insides of a 2-pin Vic-20. It just uses a 10VAC power supply instead of the newer versions that use a DIN connector that supplies 5VDC and 9VAC.
Here’s the problem child:
Everything else was replaced since it was opened up, and I had the caps. There aren’t many to replace either, I think around 7?
I did the 128 this morning, but didn’t take and pictures. There are a fair bit more to change, but not bad. Maybe an hour or so.
