Commodore PET 4016 upgraded to 32k. Refurbished with fantastic help from here:
https://www.vintage-radio.net/forum/showthread.php?t=218958
I got help which included the creation of a 6502 zero page RAM tester that didn't exist for PETs - 45 years after the PET was made.
Several chips replaced including most of the RAM and four out of five of the 40 pin chips. And a new label applied as the old one had gone.
Thanks very much to @simon_brooke for letting me have it.
Die Besitzer von #Commodore bieten einem YouTuber statt einer #Lizenz wohl plötzlich den #Verkauf des ganzen Unternehmens an. Der ehemalige Hersteller des #C64 könnte damit in die Hände von Fans gelangen. https://winfuture.de/news,151477.html?utm_source=Mastodon&utm_medium=ManualStatus&utm_campaign=SocialMedia
If you have a thing for tiny racing cars and retro gaming, here‘s Micro Machines for the Commodore Amiga!

Have fun! 
Mend It Mark is at it again! Fixing a pretty beat up 1992 #Commodore #Amiga 1200. 1h18 minutes, and I don't regret a single second.
I was playing around with the Mega65 emulator. It's the first BASIC I've typewritten since the 80s and it was fun. Maybe I'll buy one of these modern retrocomputing like machines 
The listing is the Monster Chase Program from the book Stimulating Simulations by C. William Engel.
Sad to read that Bill Atkinson has passed away. I was a Commodore kid in those early years of the digital revolution, but my all-time favorite pixel editor, the Amiga's Deluxe Paint ("DPaint"), was inspired by Bill's MacPaint.
If you'd like to (re)try DPaint, there's a great resurrection of it in the shape of @PyDPainter
Jurassic Park AGA isn't overly polite, but at least you know without a doubt what you're doing wrong. I like it!
While sorting through my collection of Amiga games, I just ran into another issue: OCS/ECS vs. AGA games. AGA stands for "Advanced Graphics Architecture", in comparison to OCS/ECS, which refers to the "Original/Enhanced Chip Set". AGA usually looks a bit better with support for 256 colors and was only available on the A4000 and A1200.
The problem I just had was with a game named "ZOOL". Its AGA version is so similar to the original release, that it initially boots up just fine, even on an older A500. Everything works: The loading screen, the codewheel prompt, even the main menu. Only then it completely crashes while trying to display a colorful fullscreen animation. Over the years, this must have mislead lots of Amiga fans, because I just found out most of the community's "ZOOL" disk images are actually mislabeled as "OCS/ECS", while they are in fact newer "AGA" versions. Yes, it even confused the SPS people! Took me a while to figure this one out. 
I found a #Commodore SX-64 for a price I was willing to pay at the local #Hamfest. I love luggables!
The Commodore bands and trademarks may finally be back with a new Commodore Computer company? 
I am inept where it comes to finding someone to take over my #Commodore collection. It is a total mess right now as I can't easily sort it all out. I don't speak German to the point where I feel confident joining the German forums. If I can't find a new owner for these things, it'll mean a rough thousand tapes, floppies, and A500 diskettes with various software will bitrot away, caps and batteries will deteriorate, and I might as well trash it all. Help? #Help #commodore64 #retrocomputing
Um ok, so I am a #Commodore kid, if you were a Apple/Commodore user in the 80's you know what that means. Over the last few years I find my curiosity for the other side is growing to the point of where I am now acquiring as much Apple // as Commodore! I am loving it too, WTF!?

After all this time, SimCity still is one of my favourite video games ever. And after all these years of collecting, I am still finding new stuff!
Today, I just came across a pristine copy protected disk image of SimCity v1.1 for the Amiga. That one will happily run the game without the need to get any codes from the manual. Also today, I found a slightly more modern version of the Terrain Editor documentation, where they removed the instructions for ATARI systems. "Imho" an interesting bit of gaming history!
Yep, I guess I'm a nerd. 
Promo flyers for #Commodore 64, 801 matrix printer and 1520 plotter. As you can see they’re pretty worn out. I had them as posters in my bedroom when I was a kid.
I think I already had a C64 at that time and eventually got a matrix printer.
I had so much fun printing banners on listing paper.

Martin Ulrich, one of the developers of the classic #Commodore #Amiga game Ports Of Call, has passed away at the age of 76.
PoC was the second game I ever played on the Amiga. Thank you, Martin, for all the good times I had playing this with my friends.

VIC-20 image quality comparison with and without the TheRetroChannel video mod. The improvement is quite dramatic in most cases.
Although the comparison here shows SVideo, the improvement over composite is almost as substantial.
Note: this post was NOT sponsored by @futurewas8bit 
Last night I installed the TheRetroChannel 
VIC-20 SVideo/Composite board in my "VC-20".
It went relatively easily, although I should probably clean up and add some fresh solder to the pins around the video socket sometime. But it works for now. Comparison screenshots coming up next! 
RetroComputing folks of Mastodon, can you help this meerkat understand why the Commodore 1541 (a) was so slow, and (b) was it was never officially "fixed" during the C64's life (i am excluding fast-loaders, e.g. Final Cartridge III)?
Note that I am aware of the 6522 serial shift register bug (per this article https://spectrum.ieee.org/commodore-64)
