…Still Learning the Craft

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

Commodore 64 capacitor modification by exchanging the old electrolytic capacitors with new ones.

The C64 Capacitor Mod

December 20, 2017August 13, 2015 by MtnBuffalo

Despite the differences in opinion on the online forums regarding the exchange of the electrolytic capacitors, I always put in new ones when repairing a Commodore 64 board. I do not believe that exchanging them would do any harm to the board besides (hopefully!) prolonging the total life span of … Read more
