I Bought A Microscope From China. PLUS: Lets Build A BlinkenBus!

I Broke my Commodore 64C, but can I fix it? Tims Retro Corner 2024-08-22 | So I managed to "k word" my 64C during the making of my last video. Either I plugged in/unplugged the cartridge I was working on without checking the 64 was switched off, or I got it at a bad angle, or something. I'll be honest, I don't exactly know what. But regardless, it ended up totally inoperative with just a black screen.So now I have to figure out exactly what got fried, and fix it.

Lets Turn a Commodore 64 Into a Retro Chip Tester Tims Retro Corner 2024-07-24 | All the PCBs used in this video came from pcbway.com Thanks to them for sponsoring this video.The Commodore 64 is so much more than a games machine.I recently bought a batch of 6532 RIOT chips to use in another project. (RIOT - RAM I/O Timer. Think of it as similar to the C64's 6526 CIA, but with added RAM), and needed a way to test them. Not being able to afford the likes of the Retro Chip Tester Pro. Surely I could design a cartridge to take a 6532, and then write a program to test it? In BASIC even?Watch and find out!Big shout of thanks to André Fachat, John Riney, and other on Big Herd's Discord, for help with this project.

Commodore 16 64K Upgrade by Tynemouth Software Tims Retro Corner 2024-06-27 | Dave from Tynemouth Software (makers of the MiniPET, Minstrel 4D, and many of the gadgets from TFW8b) asked me if I'd be interested in checking out his new 64K RAM card for the Commodore 16. Having just acquired a C16, of course I jumped at the chance.The C16 was a cut down version of Commodore's Plus/4 TED 'business' computer. It didn't have the (admittedly not very good) business software suite that came in an internal ROM, it only had 16K of RAM, not 64 (only 12K usable) , and it had a rebadged Commodore 64 case instead of the more sci-fi looks of the Plus/4. But it was cheap, and that made it a big hit for sure in parts of Europe.The lack of a Function ROM can be argued as no big loss. But the memory... let's just say there's no such thing as 'too much memory'.Thanks to Tynemouth for providing the expansion free of charge. Now, while I am a Patron, this is still my unbiased commentary, and Tynemouth have had no say in the content, nor have they seen or approved this video in advance.Tynemouth's blog post on the 64K expansion: http://blog.tynemouthsoftware.co.uk/2024/06/new-commodore-16-internal-64k-ram-upgrade.htmlBuy one: sellmyretro.com/offer/details/64324If you'd like to help support this channel, please check out my Patreon.

Can you test a CPU with a handful of spare parts? Tims Retro Corner 2024-05-31 | Big thanks to pcbway.com for sponsoring this video. I bought a batch of 6507 microprocessors from China for another project. But do they work? How can I test them? The 6507 is well known for being used in the Atari 2600, but I don't have one, so I need to think of another way to test them.A technique I've used before on the Commodore 64 and VIC-20 is the 'NOP Tester'. Essentially this is a ROM replacement that hardwires the data bus to 'NOP', which moves the CPU to the next address. This will cycle through every address, which can be measured.Sure it's a quick and dirty test, and in no way comprehensive. But can I build a NOP tester and test this batch of 6507s? Let's find out...If you'd like to help support this channel, please check out my Patreon.

Atari 65XE Restoration...ish Tims Retro Corner 2024-03-15 | Thanks to pcbway.com Great PCBs from $5. Sometimes a restoration goes really well. Other times, not so much.Now, although I'd seen Ataris in the shops ever since the 400 and 800 came out, I didn't know much about them and I'd certainly never used or owned one. Enter the 65XE, This is Tramiel-era Atari. A cost-reduced version of the already cost-reduced 800XL, in a move I guess designed to out-Commodore Commodore.So when I got hold of one, I decided to check it over, clean it, retrobright it, and so on. What could possibly go wrong? Well actually it turns out, quite a lot...

Building a Modern Power Supply for the Commodore Plus/4 Tims Retro Corner 2023-11-10 | Check out our sponsor pcbway.com for all your PCB needs, starting at $5.The foot-warmer brick-of-death power supply that came with this Plus/4 needs to be replaced. Urgently. Before it destroys the computer.These power supplies are notorious for failing, and when they do, the voltage regulator shorts its output to its input, sending lethal voltages to all the chips in the computer.But we can make a brand new one that's safe and reliable. And all it takes is a 9 volt transformer, a small 5 volt Mean Well, a bit of soldering, and some 3D printing. Oh, and an LED. Because you've got to have LEDs.BTW this build will work equally well with a C64 or C128, all you need is the appropriate plug for the computer.Obligatory warning: mains voltages can be lethal. Do not attempt this project unless you are comfortable working with mains voltage and know what you're doing. The mains here is 240V, yours may be different.If you'd like to help support this channel, please check out my Patreon.

PIEEE-488 Prototype SD drive for the Commodore PET Tims Retro Corner 2023-01-16 | My Christmas/New Year "maker project" is this IEEE-488 device for the Commodore PET. Thanks to my sponsor PCBWay pcbway.com Making a PCB couldn't be easier, from just $5 for 10 boards.I enjoyed making the Pi-1541 a few weeks ago, and I decided to try making something similar for the PET. The initial prototype is sketched out on breadboard, and programmed in Python, using a Pi400.Yes I know there are devices out there that already do something similar (SD2PET and Pet Disk Max are two that I own), but they don't quite do what I want of them to in one way or another. And yes I also know the NoDiskEmu software that drives these devices can be forked and adapted. But I'm learning Python for work, and this is a learning experience: I want to figure out my own solution. It may not even work, but I'll have fun finding out!This is a bit of an experiment in trying something different: it's not a repair video; it's not even a tutorial as such. In the week or so that I allowed myself to work on it, I only got so far. If you'd like to see it go further, please comment below. The next stage would be to take it to a PCB, maybe make a 3d printed case, and of course, continue the software.🔴 *NEW!!* Follow me on Mastodon: https://retrorewind.social/@trc🔴 Subscribe to be notified of more retro stuff: youtube.com/c/TimsRetroCorner?sub_confirmation=1🔴 Buy me a coffee or make a one-time donation: paypal.com/donate/?hosted_button_id=DC2YUGZDYKHRN🔴 Blog: timsretrocorner.comMusic: Arpanauts by Eric Skiff - http://ericskiff.com/music00:00 - Introduction04:16 - Sponsor Massage04:57 - Hardware Sketch09:46 - Equipment13:33 - Intermediate Breadboard Layout17:30 - Configuring the Pi - Enable I2C19:19 - Buttons & LEDs - mini demo20:08 - IEEE Data Transfer Demo

In which I attempt to fix the floppy drive, and retrobright the case. pcbway.com - the easy way to PCB, from just $5.The floppy drive on this A600 (a Panasonic JU-253-043P) doesn't work. At least, it doesn't spin. The heads tick back & forth as you'd expect, but nothing happens when you put a disk in. Hopefully I can find the problem. And since it's the coldest, darkest time of the year, it must be time to do some retrobrighting!

Amiga 600 Restoration Part 1: Re-Capping Tims Retro Corner 2022-12-15 | I'm taking a first look at my "untested" Amiga 600. Kindly sponsored by my favourite PCB maker, PCBWay. pcbway.com On initial inspection the case looks to be in reasonable condition. Yellow for sure and there's a crack by the floppy button. But at least it's clean. Oh, and one of the two warranty seals is still intact (but not for long!)Of course that means that inside lurk those nasty, leaky, surface mount capacitors. Better get the soldering iron heated up...This is my first time with SMD caps, so the technique I'm using comes from literally minutes of watching YouTube!
