Episode 8: C128 Black Screen Diagnostic and Repair Commodore Restore 2019-07-26 | In this video, I diagnose an unresponsive C128. It shows a black screen, but the board has power. You'll see me use a multimeter and logic probe to try to find the problem, and it turned out to be in the last place I would have considered...Special thanks to Michael Myers and the Commodore International Historical Society Facebook page for the deal on the 128.

Episode 21: SX-64 Repair and Rebuild, Part VII: Reassembly, Speaker, and Fan Commodore Restore 2023-03-31 | In this video, I'll reassemble most of the SX, add a new speaker and fan with a 3D-printed mount, discuss the SIDFX addition, and show how the wiring is done. There's also a 3D-printed clip to help hold the I/O board in place and prevent it from wiggling loose from the main CPU board. One caveat: This series is being posted as the project progresses. As far as I know, everything should work when it's all back together, but I make no guarantees on that point! It's always possible that I've screwed something up in one way or another. Tune in again after a couple more videos to find out if these mods actually worked...or not. If you know for a fact that I've done something incorrectly, please comment and let me know.Links:SIDFX: https://www.sidfx.dk/Audio Amplifier: DROK 15W+15W 2.0 Dual Channel Audio Amplifier Board PAM8620Speaker: Visaton SC 5.9 - 8 ohm Fan: Noctua NF-A4x10 FLXI/O Board clip: thingiverse.com/thing:5938764Music:Ryan Andersen, "Lift It Up":freemusicarchive.org/music/Ryan_Andersen/Pop_Music/Lift_It_Up

Episode 19: SX-64 Repair and Rebuild, Part V: Handle Latch Commodore Restore 2021-06-10 | In this episode, I'll use a 3D printed solution for the missing/broken handle locking parts that are common for SX-64 users. My complete design: thingiverse.com/thing:4882384NB: I did not post to Shapeways because 1) it turns out it's way too expensive for my taste ($45 to print these pieces), and 2) it's not a great option anyway. Better to find a MakerSpace in your town or get someone to print it for you instead. Libraries also often have 3D printers for use.

Episode 15: SX-64 Repair and Rebuild, Part 1: Intro and Testing Commodore Restore 2020-12-31 | This is an introduction to a new series on the SX-64. Over the course of several videos, the unit will be disassembled, repaired, future-proofed, and undergo some mods. This video covers the (current) plan for the series and an introductory look inside the SX-64. Some quick testing at the end also. Sorry for the shaky handheld work. I'll get a different camera mount for future videos. Please leave comments with suggestions on useful mods. I'm not into the demo scene; rather, I want this computer to be something I can keep in the office and pull out regularly for a quick game or some word processing.
C128 Keyboard Repair Commodore Restore 2020-04-20 | This time, I have a C128 with a problematic keyboard. Three of the keys either don't work at all, or only work intermittently. Follow along as I diagnose it and get it working perfectly again!

Episode 12: 1541 Diagnostic & Repair Commodore Restore 2019-12-25 | In this video, I have a 1541 that, on startup, spins the spindle motor and lights the red LED, but doesn't move the head. The problem is traced to a faulty 6502 and a stuck head mechanism. I demonstrate the use of a multimeter and logic probe to find the problem. I also show the process of disassembly and how to clean and lubricate the drive mechanism. I apologize for the audio and video issues in this one. I recorded most of the footage before I realized that something must have been set wrong on the camera. The clips came out really dark, so I tried to use processing to brighten them up. There was also background noise in some clips that I didn't realize the microphone had picked up. I almost didn't post this one, but I thought that the content could still be useful, so here it is.Sams Computerfacts, Disk Drive: Commodore VIC 1541/1541: archive.org/details/sams-computerfacts-cd4-1541I’m on many of the Commodore groups on Facebook, notably the Commodore 8-Bit Repair and Upgrades page, which I started: facebook.com/groups/1954758181300269Music: Ryan Andersen, "Lift It Up": http://freemusicarchive.org/music/Ryan_Andersen/Pop_Music/Lift_It_UpA Smile for Timbuctu, "Il Circo Smorfioso": http://freemusicarchive.org/music/A_Smile_for_Timbuctu/Silly_Songs/05_-_a_smile_for_timbuctu_-_il_circo_smorfioso_kzz01_vbr
Episode 11: ZD-915 Desoldering Station: First Use and Review Commodore Restore 2019-08-21 | I recently bought my very first desoldering station, the ZD-915. It's the cheapest on the market, and it has its flaws, but overall it's a good unit for the hobbyist. In this video, I'll show my very rough first attempts at using it, and give an honest assessment of the unit. And just so you know--I still *suck* (get it?) at desoldering. I'm getting the hang of it, though.
Episode 10: Device Not Present and Searching For Errors Commodore Restore 2019-08-11 | In this video, I have a 1541 that presents a "Device Not Present" error.

Final Diagnostic Run on C128 Commodore Restore 2019-07-29 | This is the final diagnostic test on the C128. I thought I lost the footage, so I didn't include it at the end of Part II. It's just a short clip, but you can see a good test across the board, and hear the SID test complete successfully.

Episode 2: C64 Restoration Commodore Restore 2019-05-13 | Apologies for the roughness of this one. In my first video, I used an old video camera, but it can’t record in 1080. To aim for higher quality, I tried using my phone, and obviously I don't quite have the hang of it yet. I put together a rig to hold the phone over the workbench, but I can’t see the screen in that position, so it’s hard to keep things centered, and when I have to lean over the bench, I don’t know when my head is in the way! It also doesn’t hold the phone very steady, so you’ll notice some “bouncing” when I accidentally bump into it. I'm going to build a new rig before shooting the next video.I’m on many of the Commodore groups on Facebook, notably the Commodore 8-Bit Repair and Upgrades page, which I started:facebook.com/groups/1954758181300269Music: Ryan Andersen, "Lift It Up": http://freemusicarchive.org/music/Ryan_Andersen/Pop_Music/Lift_It_UpAtom Power Supply: commodore4ever.netOatey Fix it Stick: amazon.com/Oatey-31270-Tubes-Display-4-Ounce/dp/B0009QW5IU
