Restoration project, saved it from my parents place. Bit dirty but no yellowing.

Whats the go with the power supplies guys? Do you just replace them?

I had one of those supplies. I never gave it the chance to destroy my computer Go back to the bottom of page one of this thread to see one possible hack.

I logged on though to post about a SwinSID.

I had a C64 with a suspect SID (see above). Rather than pull a good one and risk wrecking it at some point in the process (or having the mobo trash it though I blamed one of the three PSUs that came with two computers...) I bought a SwinSID implementation on ebay for about $25 delivered.

It is a digital SID emulator that is available as a drop in replacement (no paddles though for Arkanoid, oh well). It removes the analogue output charm of a C64 so I was a bit skeptical but it seemed better than the other options (including potentially broken or partially broken units for sale on ebay). Also it is interesting in its own right.

Installation was simple. One jumper for the two kinds of SID and an outline in the silkscreen showed me 'the end with the notch' to properly orient it. I now have sound and one confirmed dead 6581

The verdict is that it sounds awesome. I can't pick any differences between it and the real thing so far except that it a little too hifi There are some AB comparison videos on youtube that show some more significant differences but the firmware is improving all the time. I plan to solder on a header to keep it updated with a USB to TTL serial adapter I have.

SwinSID FTW.

EDIT: Firmware improving all the time may have been an exaggeration it seems. Still good already though

Cheers for that!

After a good clean I made a box that could feed the power from a Snes PSU and a USB cable.

Wake up old man:

Nice one. The fuses and capacitors I put in are overkill. It appears though that we both buy plastic boxes at the same retail chain.

I've wondered about the Swinsids - good to have some first-hand experience. We need more chips re-implemented as drop-in replacements. At the top of this list I would put the TED chip for Commodore PLUS4/C16's. Those TEDS are fragile, self-destructive (even when powered off!) - and there's no replacement for them. I am terrified that in a few years we'll only have software emulation to enjoy..

It always warms my heart to see another Commodore resuscitated. I'm very glad you didn't use that old power brick. They're widowmakers..

I did wonder about that!

Ordered an S-Video cable and an sd2iec today. Super hyped to play some of the games I loved as a kid again and show them to my son.

Emulation? Oh the humanity! I have heard ted is fickle.

A C64 nut I know (springystick on these forums) had a listen to my swinsid through some hifi gear on the weekend. He thought it was awesome. I still prefer the signature misbehaviour and fidelity problems of the genuine article but honestly it is very good indeed. I have seen PLAs and ROMs for the c64 too (I suspect you have too Callan).

Nice stick nimmers (looks like you made another trip to jaycar for the box ). I use these ones with buttons on the stick.

The clip over hoods that you can get for the 9 pin connectors prevent proper insertion of the plug. I have had good results with sanding the little hooks down a bit with a bit of a bevel and better results by cutting them off and getting adventurous with the hot melt glue inside the shell...

Edit: not sure how old your son is Nimmers but my four year old boy is nuts for Buggy Boy with unlimited time.

Edit2: WarrenR the C64 reloaded motherboard should be pre-order-able any day. It might suit you

Brand new C=64C cases made from original molds on Kickstarter. Someone please find the 'breadbin' moulds, I have lots of nice kit in lots of bastardised and damaged cases.

Bit of an update on the swinsid too. I have a C64C that I believe to be working fine. However, Grand Prix Circuit's distorted guitar etc. sounds better on the swinsid than the sid in the C64C (the 8580). I will trial another C64C but I think it is to be expected based on wikipedia's SID entry "many SID musicians prefer the flawed 6581 chip over the corrected 8580 chip. The main reason for this is that the filter produces strong distortion that is sometimes used to produce simulation of instruments such as a distorted electric guitar."

Some serious weirdness spied inside a C64 PSU I picked up last night. I took the lid off and look!

Is that a custom aftermarket switch-mode 5v side? The heatsink even sits top to bottom inside the case by the looks of it. Neat! Note the two different colour cables for the 240v and C64 sides.

It is an external Commodore 128 power supply, with a C64 cable grafted on the end of it, and the label transferred. The schematic (I think!)can be found HERE.

It's a linear design, not switchmode, but it's still lot better built than the C64 widowmakers, so you've done well there. It's got more headroom than the standard C64 PSU as well, and has enough oomph to support a REU if you have one.

Here's a picture of a C128 external PSU in my collection:
Innards:


Note the different colours for the wires in the output cable.
Case:


Note the reversed colour scheme of the label.

Nice score

Callan

I'm currently using a C128 PSU for my C64 too. The 128 PSU's case was cracked when I bought it, which caused a louder than normal hum, so I transferred the guts of it into my old C64 PSU. Classic Commodore move, re-using whatever they could - they just changed the sticker on top.

I didn't chop the cable though, I'm using an adapter that I bought on the interwebs:





I'd like to build or buy a modern replacement for this PSU one day, I've come close to going down the wall warts option a couple of times but it always seems a tad too hard.
