KOJRO Retro innovations | Interlude to part 9 in The Commodore 64 resurrection series. Building a PSU tester. @kojroRI | Uploaded May 2022 | Updated October 2024, 3 hours ago.
This is an interlude to part 9 in a series of videos where we celebrate the 40-year anniversary of the Commodore 64 by doing a bunch of repair videos. This time we continue to do something totally different as it seems that the last videos in this series has started to lose some interest. We build a tester for the C64 power bricks, that not only measures the voltage but also provides a “dummy” load so that we will be measuring in real life conditions. I usually rebuild these power supplies, but I do have some that are not opened yet. But a lot of these just get trashed as they have a terrible reputation. In the next video we will find out if this is justified. So in this video we do some electronics basics, build the PSU tester, and test the circuit.
I have a lot of old C64’s both single motherboards and complete systems. Nearly all of them need some kind of attention now, and many of them have been neglected now for the best part of 30 years and shows the sign of that. In the prequel to this series I did build a SixtyClone board to have as a reference, and tool to test chips and other peripherals. I do appreciate feedback, and I find it difficult to maintain a good rhythm on these repairs, so some pointers will be appreciated. So happy birthday C64, and as an appreciation for the community and the future of the remaining C64’s out there. Here is my number 8.1 video in the C64 Resurrection series, so let’s celebrate our favorite 8-bit computer. #C64 #DIY #commodore
