Building a Replacement Commodore 64 Power Supply In this video, I build a replacement power supply and discuss problems with the original supplies. I also discuss the voltages used in the classic Commodore 64 8-bit computer. Update: I have a follow up video planned that will have information on building a power supply tester as well as a quick look at a fully-failed black brick of death that came with an eBay machine. This is currently planned for late May due to delays in getting the parts for the tester. If you just want to purchase a replacement power supply, or a C64 Saver then I whole heatedly recommend Ray Carlson. http://personalpages.tds.net/~rcarlsen/cbm.html In a future video I will build an S-Video to HDMI setup and then refurbish this classic vintage computer and a 1541 disk drive from the 1980’s. RavenWolf Retro Tech gives you a new vintage tech video each week. From Retro Computing to older tech, such as the 1917 phonograph, 1916 Kilowatt meter & 1972 Tektronix Oscilloscope I have on hand. We will explore & restore vintage technology every week. I will be giving you new videos, as I can, until the shop is completed. After that, I will release a new video every week.

This Commodore 64 has some serious issues. Today we'll look at a messed up machine and I will cover the typical steps I take when I restore a machine. We all know that these old computers did it better!

In this video we restore the A501 RAM expansion for our new Commodore Amiga 500. This card has some damage from a leaking battery so we fix the damage, replace the capacitors and install an alternative battery solution that should not leak in the future. We also discuss the mod done to the Amiga 500 that changes the expansion from providing pseudo-fast (slow) RAM to chip RAM accessible to the customer chips like Fat Agnus and Denise.

I ordered the capacitors, along with a bunch of other goodies, a couple weeks ago from Retro Rewind but they seem to have been lost in the black hole that is the USPS in Chicago. At least the replacement socket for the Motorola 68000 is here!
