I use an old c64 brick with my vic20... the 5v tends to fail on these but
you can use the 9-10VAC still.

Finally dug out the VIC-20, C-64, and 128. I have no idea if they still
power on and "how much".
The VIC-20 uses the older style (2-prong) plug and is labeled 9V. I don't
have the original supply, but I assume I'm looking for a 9V 3A one.
1) I saw on eBay some 11.5V supplies but those are probably for a
different model.
2) I saw a video where someone took a Honeywell CCTV supply (I saw one
that was 9V, 2.5A) and just used a standard two prong connector + plastic
to hold down the switch.
Do you have any better ideas on a replacement?
The C64 came with the gel-filled power supply (no screws). I have a
second 3rd party one from the same era that I would trust more. I saw
people simply running a multimeter test over the 5V pins (the problematic
one), but then I saw someone running the test over a load for further
testing. The resistor he used was huge.
1) Is the pin test good enough? Or should I just assume they are bad and
get a new one? If I get a new one, I've seen a couple of companies making
new supplies. Any recommendations?
The C128 came with a supply that is the same shape as the Amiga 500, just
heavier. Do these have the same issues as the C64 ones, or because a C128
is relatively rare no one really bothers with making C128 supplies? It has
a square connection, versus the round one on the C64.
I really don't want to buy a diag cart and harness just to "prove"
everything this functioning. Is there another way to test them, like going
through a standard battery of use-cases?
Thanks.
