I'm a computer programmer who recently started getting interested in learning more about old computer systems, and trying to fix them up as a hobby.
I started this channel mostly as an extension of the hobby, and to share what I'm doing with people. I'm not sure how regularly I'll be uploading videos, but I'll hopefully have a steady trickle of content rolling out!
Very painful to watch as a competent electronics and pc engineer. Please buy some. Liquid flux solder sucker and maybe a small heat gun for multi legged components .
Very Interesting that you can even power up the VIC-20 by reversing the power flow through the userport. I did not even know that this was even possible. In the video, Because you are using PAL, Some VIC games like GORF were created for NTSC format, so to compensate, PAL machines can move the screen using the cursor keys or joystick to center the screen. Also, The reverse is also true, If you are in NTSC and run a game originally created in PAL format and run it on an NTSC machine, It will do the same exact thing for NTSC users. IT was just an ingenious way for the machine to compensate for NTSC vs. PAL Format differences that is in the VIC's design. Also, I noticed that while your VIC does not have the RARE PET Keyboard, IT DOES have the RARE Unobtainium PET keyboard Shift Lock key switch, which was used on a few rare updated keyboards. That switch alone (If it is working and locks) is worth more than your entire VIC-20 itself. No lie. You might want to Keep that switch for yourself, or pick up a newer VIC or C64 keyboard that has a newer Shift Lock installed, and Sell off the VIC Keyboard you have because it has the uber rare PET Keyboard Shift Lock installed in it. Just letting you know! And finally, I think your problem with your VIC is the Character ROM or BASIC ROM chips. They should both be socketed for easy removal and replacement. Tony K. ;)
Thanks a lot for the info! Since the video I had learned that fact about the adjustable display, very interesting little feature there. Hoping to get back to this project soon, real life took over for the last year or so unfortunately
Mono connectors can sometimes be called TS (tip-sleeve) connectors And stereo connectors can sometimes be called TRS (tip-ring-sleeve) connectors en.wikipedia.org/wiki/Phone_connector_(audio) And my keyboard actually uses a TRRS cable to connect the two separate halves, fun!

hello, as well as being your new subscriber, I welcome you to the owner club of this fantastic expansion! I also made some videos about it. My vic 20 arfon has a PET keyboard and a VIC gold-ceramic chip. The arfon expansion card is still a prototype, ie without the manufacturer's logo! I would like to leave you some links here, where I try it with demos, but I believe that the YT algorithm can eliminate the message if I insert links
"I don't really know how to solder." followed by "my understanding is flux is a bit of cheat". So much wrong here, flux acts like primer preparing the surface to bond strongly to the solder, not using solder risk dry unreliable joints. Could do with a solder sucker. Still, a competent repair.
"a competent repair" - I'll take that hahaha. Thanks for the clarification on flux, I think I've got my head around it more than I did when filming this video, but I've still got a lot to learn. Definitely looking to get something better for desoldering, using the wick really becomes a pain.
I'm pretty sure I cut myself every single time I opened my computer back in the 1990s and 2000s Did the average computer case get friendlier after that, or did my change in income mean I could buy higher quality, or did I become more cautious?
Ah, back when people engraved their initials in the plastic to try to thwart thieves I remember my parents doing this in the back of our TV and other expensive stuff
Interesting. That was an expensive thing in 1982. The apple II floppy disk set was amazing when i first saw one. To move on from cassete tapes seemed a big leap. :)
I like that there is a decent amount of realness not edited out. The human aspects of failing and figuring out a solution is easier to follow for me personally.
I did cut out quite a bit of miserable failure while trying to wick off the old solder, but tried to keep enough in to show that I'm still figuring things out and not everyone is an expert. Glad you liked it!
