I remember those black and red clips when I installed a Batteries Included Bus card. The bus card allowed me to hook up an ancient Commodore Pet 3022 Tractor Printer for use with their Paperclip 64 word processor. I did most of my University essays using these Batteries Included products. Dox Matrix 5x7 pixel printing. Useful at the time but a dinosaur today. You can Google "batteries included bus card manual pdf" and I believe you'll see it's a match on page 3 of the manual (pdbuchan dot com). Bus card provided Basic 4 and Disk commands (rarely used it for this). I believe the 3022 was an IEEE device and I used it for this connectivity.

That white stuff was probably white grease pencil, used to mark chips. The problem with this stuff is it melts and gets soft, then runs. That stuff on the bottom looks like it was dried beer or tea. Coffee and coke leave a much darker stain. Regarding cleaning the cassette and user port pins, try Brasso. That stuff works miracles on brass, and adds a molecular corrosion resistant coating.

It always makes me so happy to see that blue screen of Commodore goodness come up when the power switch is turned on, especially if the board was previously dead. Good job getting that thing cleaned up so well, and getting it up and running. As a suggestion, I'd say to always attempt to fix C64s before designating them as for-parts, because as this video shows, it can be a very simple fix. Only those boards where every attempt to fix it turns up nothing, or there is unrepairable physical damage, should be used for parts. As long as you have the spare parts and the know how for fixing them, it's always worth it. Now, sometimes it's not the board but instead is the case, keyboard, etc. that are damaged beyond repair. In cases like that, the boards can be fixed and put into storage for replacing the motherboard in future C64s that have a good case and keyboard but the board can't be fixed. And as far as the damaged cases and keyboards, those can be saved for salvage, too.

A couple of notes: (1) a black screen can be caused by one or several faulty chips on the C64 mainboard; go to personalpages.tds.net/~rcarlsen/cbm/c64/c64-ic.txt and doe a search for the word "blank" (F3 on most browsers) and you will see other chips to look at; (2) make sure your power supply is not outputting more than 5.2V -- that's about the upper limit before C64 ICs become problematic and are susceptible to a shortened lifespan or outright failure; (3) consider getting a C64 over-voltage protection device like bwack's C64 Saver, or the SaV64 -- these devices will save your C64 if the original power supply ever fails and outputs more voltage then it should. I hope this helps. Good luck!

Hey Craig. Thanks for the positive feedback and for commenting. Hmm, your C64C is presenting some very strange behaviour. A standard blue/light blue screen with no BASIC post can indicate a problem with the BASIC ROM, but it almost sounds more like the system is still getting a trickle of near 5V after being turned off. I assume Centipede is the cartridge version? Do these symptoms occur if you switch _off_ the computer and then physically unplug the power supply plug from the computer, as well? If the issue does not reoccur I would look at the switch itself -- maybe it's poles are not disconnecting completely allowing a trickle of 5V to be supplied. Depending of the switch most can be desoldered and then dismantled allowing you clean the switching mechanism. In fact, @bwack has a great video of how to do that, kzread.info/dash/bejne/gaeh2JZsZ5nPiaQ.html. I would start with this and see how if anything changes...for the better. Are you on Twitter at all?

It's a nice design however the 9VAC output runs rather high and can be a problem with some C64 motherboards that do not have their voltage regulators factory heatsinked to the board. The regulators can get very hot and unstable reducing the voltage to the required levels because they cannot dissipate the excess heat.

Typically, most ICs that fail on a C64 will get really hot (even to the touch) very fast, so if you have access to a spare PLA or PLA replacement, like PLAnkton, then swapping out the old for the new is a good place to start. However, as will most C64 _black_ _screen_ faults, it might be one or more ICs causing the fault. Is there any chance you have or could get your hands on a Dead Test cartridge? Available on eBay, ebay.to/2zVxurj. Even without the full diagnostic harness, the Dead Test will identify faulty chips, like DRAM, PLA, SID (actually, you should pull the SID and leave it out during troubleshooting and repair, as it is not required for the C64 to power up normally and there is no sense risking damage to it). If the Dead Test cart does not start at all then you likely have a bad CPU. I hope this helps. /\/\FR

No, absolutely not! It's the right german word for that kind of schmutz :-) btw it was very nice to see that C64 came back to life again.

Oh, good. "Schmutz" does reside in my general vocabulary -- it's one of those great words that sounds like what it describes. :) I am glad you liked the video -- thanks for watching and commenting. Hopefully, you are a subscriber; I have more C64 fix-its on the way. EDIT: I see you have subbed! Thank you very much!
