Commodore 64 power supplies reparable

More Power!

November 19, 2016February 16, 2016 by MtnBuffalo

I recently posted images of the different Commodore 64 power supplies (PSU) that I have in my collection. I thought they pretty much represented all the European versions out there and that the so-called ‘repairable PSU’ version was something that was mostly released in the US. So I … Read more

C64 Power Supplies

August 26, 2020January 6, 2016 by MtnBuffalo

Commodore produced a fair amount of different looking power supply units (PSU) for the Commodore 64 home computer. I have collected some of the most common versions from the European market in this post to show some of the differences between them. All brown/greyish PSUs were … Read more

SD2IEC μ1541 Drive

April 20, 2020January 4, 2016 by MtnBuffalo

Scrolling through a local second hand site, I came across a guy who had made his own version of the SD2IEC device. The SD2IEC is a mass storage solution which uses a SD card for data storage (i.e. games and programs) and interfaces with the IEC bus. It does … Read more

Power LED Colors

May 6, 2016January 2, 2016 by MtnBuffalo

I have noticed that the different versions of the Commodore 64C’s have various power LED colors. I do not know if Commodore was consistent with the LED colors of the different board revisions of the Commodore 64C’s, but these are the colors that the power … Read more

Mod of the Year 2015

November 11, 2020December 14, 2015 by MtnBuffalo

…well almost… The machine still needs some new colored keycaps (hurry up Phase5!!!), a domed sticker at the bottom and a cold reset button using an Arduino Pro Mini. But I gotta have some modding goals for 2016, right? This machine has been build from … Read more

3D Prints for the C64

April 26, 2016November 21, 2015 by MtnBuffalo

Going through my ‘stockpile’ of Commodore 64 bits and pieces, I realized that several 3D printed add-ons have found their way into my precious Commodore 64s. I therefore decided to grab the 3D prints that I have, shoot some photos and describe why 3D prints for the … Read more

C64 RaspberryPi Mod

December 18, 2017November 18, 2015 by MtnBuffalo

For some reason I had a Commodore 64 breadbox case, a RaspberryPi and a Keyrah PCB filling up my spares box. I really can’t say why my spares box is so well equipped, but this is how I got on the ‘C64 RaspberryPi mod’ wave. … Read more

March 16, 2016November 6, 2015 by MtnBuffalo

I just finished working on an Assy No. 250425 longboard. The problem was the standard ‘black screen of death’ and it all ended up with me fooling myself on the way to success. The faultfinding process can be frustrating, annoying and a pain in the … Read more

Stack of Broken C64s

January 15, 2016November 4, 2015 by MtnBuffalo

I recently got my hands on a stack of non-functioning Commmodore 64s cheap off the internet. Buying retro gear like that is always a good way to re-stock the spare parts box and hopefully get some of the machines to work again. This time I was … Read more
