Commodore Project 64 Part 9: More Keyboard Stuff

Despite all of the other neat stuff I've been discussion on this site, I have been continuing work on Project 64. I've had a bit of luck with one of the non-working boards that hadn't been putting out any video. It's still not working correctly, but this is what it's showing now:
This was after replacing several chips on the board. The troubleshooting guide suggests this is a RAM issue, but so far replacing those hasn't solved the new problem. I've ordered more chips to see if this fixes things, so we'll see.

Meet the Machine: The Commodore SX-64 Executive Computer

Holy crap. I got a Commodore SX-64!
Today's post isn't going to be particularly informative or productive. I managed to get my hand on what has been my holy grail for vintage computer collecting. I never actually thought I would own one of these. This is a computer I have only ever seen in person once before and it wasn't working. And now I have one in my possession that works perfectly.

Radio Shack Robie Junior: A Robot from 1986

This may come as a shock to people who know me, but I love robots. I'm the kind of person who immediately feels empathy for a robot in distress despite knowing full well its conscious is just lines of code written by someone. I don't care though because they're great. I'll gladly accept them as our overlords when the singularity occurs.

I recently found this Robie Junior Remote Command Intelligent Robot at a yard sale for $5. I knew I had to take him home with me the moment I laid eyes on him, just sitting there mixed in with a bunch of other toys and junk someone didn't want anymore. I had no idea what I was really buying at the time. It was missing a remote control and manual, and it didn't look like it was in great shape, but at the very least it would be a cool thing to have on display.

Power Mac G4 Part 3: Cleaning

After many hours, I have completed the cleaning and rebuilding of the Apple Power Mac G4. This was a much more difficult process than I had expected it to be, but I still enjoyed it.
Using an electric duster, I sprayed air at the electrical components to remove much of the debris. This ended up working really well and I only had to use a small amount of isopropyl alcohol to clean some of the tougher spots.

Power Mac G4 Part 2: Teardown

Last week I mentioned how easy it was to get inside the Power Mac G4 with its latch and hinged side. This remains true, but to completely tear down the machine, it was a hell of a lot more difficult than a modern Windows PC. But this needed to be done so I could get the interior of this computer as clean as possible.

I started with the DVD drive because it's the most easily accessible component. It's not screwed in or held in place with latches or anything.
