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.
