It’s finally time to show what has been clutting up my workbench for way too long! Back in 2015 I got my hands on two C64 Reloaded boards (link) and installed them inside cases from the Kickstarter campaign (link). I also entered the Phase5 Indiegogo … Read more

The PLAdvanced+

June 25, 2018 by MtnBuffalo

This may come as a shock to some, but the sad news is that the old chips inside a Commodore 64 will eventually fail!! Most often the chips will simply die due to old age or other external factors like a faulty power supply. When … Read more

Floppy Backup

April 8, 2018April 7, 2018 by MtnBuffalo

Are Data Back-ups for Sissies? Some of us still have heaps of old 5.25″ floppies laying around. It is well known that data stored on this type of media is not the safest place to keep it. While most of the data can quite easily … Read more

C64 Keyboard Prototype

March 29, 2021March 16, 2018 by MtnBuffalo

It has been almost two years since I boldly announced that I would make new keyboards (link) for my C64 Reloaded boards (link). I have now realized that making new keyboards is by far the biggest Commodore 64 project that I have ever gotten myself … Read more

C64 Case Modding

December 18, 2017August 11, 2017 by MtnBuffalo

Montezuma’s Revenge is by far my all time favourite game for the Commodore 64 (link). Maybe it’s because the gameplay is so simple. All you have to do is find keys, open doors, don’t get killed, get to the bottom of the maze, repeat… In … Read more

A Plethora of PLAs

July 5, 2018December 19, 2016 by MtnBuffalo

The most common cause of a black screen on the old Commodore 64 long boards (link) is a broken Programmed Logic Array (PLA) chip located at position U17. Based on different input signals, the PLA creates chip select signals and controls which chip is to … Read more
