My Commodore 64 Repairs

So i have a 90 percent not working 6581 SID. I dont want to throw it out....can anything be done with it? It sometimes plays a few beeps but usually does nothing.
 
I doubt it. I just did a video of trying to bake Gorf Customs in the oven to see if it revived them. You could try the same with the SID. People have have said it has worked on pokeys.
 
I need to get back into my C64 again. I'm looking at mine now and it has a broken key on the keyboard. I'm guessing that can't be replaced, or can it? I'm also missing all the power cords and such. So it's just the keyboard and what's inside.

Recently I came across this guy repairing C64s on Youtube. Pretty interesting stuff!

You can definitely replace the key and the plunger thingy. Whatever you do be careful washing the keys. I filmed fixing a few keys along with ruining quite a few :)

You would have wanted to get a new power supply anyways.
 
Speaking of power supplies...i bought a new one. I have the original one but obviously it isnt working properly. It needs to be serviced but since the whole damn thing is encased in an epoxy resin of sorts, you cant get at it. It is a PAL commodore so its a 220v plug. Should I just toss it? @thegleek, i may need your emotional support here. Do i keep it as part of my collection to say "yes here is an original power adapter...but you cant use it"? Or toss it?
 
FWIW, I make test carts for C64s with the 781220 and 586220 test programs on it. You can pick either one with a switch... I also make EPROM adapters for the kernal ROM (or BASIC), and ROM adapters where you can select between two kernals...

And for SID replacements, I like the SwinSID Ultimate (regular SwinSID isn't that great from what I've heard of it, but the Ultimate is near perfect)

I repaired my C64 last year and had to make a few things... well, either make them or import them from EU since there weren't any US sellers at the time.

i forgot the one i originally bought years/decades ago that was a repro/aftermarket, i'll have to dig it out...

but searching gave me 2 of these:


 
I loved that thing.. I was pretty good at 6502 assembler way back then.. Even hacked a game once and wrote some good code for other things..

I have a Versa64Cart with only the deadtest bin on a 2764. Do you happen to have a bin with more test programs already merged for a 27512?
 
wow. wonder how many you can possibly daisy chain?
Didn't see anyone answer this... so the answer is 4 on a standard 1541.

Drives can be device #8, 9, 10 and 11. There are two pads inside the drive. So you cut (or maybe it was bridge) one or both of the pads to change the device number. As a kid I installed a switch in one of my drives so I could switch it between 8 and 9 since I sometimes shared it between my Vic20 and C64. I did have all 4 drives at one time too which I ran a BBS off of (which I wrote and I still have).
