How to bootstrap a TPDD2 - Tandy Portable Disk Drive Josh Malone 2020-06-29 | A very quick video showing how to bootstrap / initialize a Tandy Portable Disk Drive 2. This procedure is much simpler and faster than the TPDD1.For a video on the original TPDD, see youtube.com/watch?v=ClqOefUSuTU
Scaler shootout: RetroTink 4K vs Batman Forever (2011, Batman Group) on Amstrad CPC Josh Malone 2024-03-16 | This video is part of a set of videos where I challenge my various video scaler devices to handle the 2011 demo "Batman Forever" on Amstrad CPC. This demo is notorious for being difficult capture properly due to its use of odd video modes and fast transitions between modes. I wanted to see if any of my devices could handle it properly.The demo is running on a real Amstrad CPC-464 with a DDI-5 disk interface + RAM expansion. The scaler in this video is a RetroTink 4K running firmware 1.3.4 and with settings tweaked as best I could to handle the signals from the CPC. (There's probably room for improvement in my settings, TB)The video is absolutely un-edited and no cropping or scaling was done during the capture. The image was scaled to 1080p50 by the RetroTink 4K and captured with an AverMedia BU110. The RetroTink 4K settings are shown at the end of the video.Audio is captured from the CPC by an external audio mixer (due to capture issues which I've since solved) and is processed realtime by OBS to reduce the stereo panning (just to make the video more listenable).The RT4K did an admirable job capturing this demo, though not without considerable tweaking. It was the only scaler I have that did an acceptable job on the interlaced image near the end. If you have advice on how to improve the RT4K capture settings for this demo, or on the CPC in general, feel free to reach out via https://retrorewind.social/@48kRAM
Scaler shootout: GBS-C vs Batman Forever (2011, Batman Group) on Amstrad CPC Josh Malone 2024-03-16 | This video is part of a set of videos where I challenge my various video scaler devices to handle the 2011 demo "Batman Forever" on Amstrad CPC. This demo is notorious for being difficult capture properly due to its use of odd video modes and fast transitions between modes. I wanted to see if any of my devices could handle it properly.The demo is running on a real Amstrad CPC-464 with a DDI-5 disk interface + RAM expansion. The scaler in this video is a GBS-C All-in-one (Retroscaler version) with built-in HDMI output. Settings on the GBS-C are tweaked as best I could to handle the signals from the CPC. The video is absolutely un-edited and no cropping or scaling was done during the capture. The image was scaled to 1080p50 by the GBS-C and captured with an AverMedia BU110.Audio is captured from the CPC by the GBS-C and is processed realtime by OBS to reduce the stereo panning (just to make the video more listenable).The GBS-C probably did the poorest capture job, in my opinion. The interlaced graphic near this end is particularly difficult, but it also took a while to sync to the graphic at 3:20 and the overall image quality I feel is poorer.

I wanted to see if any of my devices could handle it properly.The demo is running on a real Amstrad CPC-464 with a DDI-5 disk interface + RAM expansion. The scaler in this video is a RetroTink 5K (early version) running firmware 3.92 and with settings tweaked as best I could to handle the signals from the CPC. The video is absolutely un-edited and no cropping or scaling was done during the capture. The image was scaled to 1080p50 by the RetroTink 5x and captured with an AverMedia BU110. The RetroTink 5x settings are shown at the end of the video.Audio is captured from the CPC by the RT5x and is processed realtime by OBS to reduce the stereo panning (just to make the video more listenable).If you have advice on how to improve the RT5x capture settings for this demo, or on the CPC in general, feel free to reach out via https://retrorewind.social/@48kRAM

Livestream: Tandy Color Computer 3 recap Josh Malone 2022-02-20 | Wherein we replace the electrolytic capacitors on a Tandy CoCo3, and almost - but not quite - get the special capacitor in the wrong place. This is a highlight from a live Twitch stream from Feb. 15, 2022.Thanks to Frank from RetroRewind for his help identifying the cap locations. (Note: This stream is not sponsored; the capacitor kit was purchased by me.)
Apple 2c auto-loading BASIC code from an Tandy 100 Josh Malone 2021-07-23 | In this video, I demonstrate my too-late-to-qualify, deadlines-be-damned "slackfest" entry for KansasFest 2021. The Apple 2c boots from a disk and then a message to the Tandy 100 asking for some BASIC code to run. The Tandy chooses a random program (from several that I obtained from http://www.deater.net/weave/vmwprod/appleiibot) and uploads the code to the Apple 2c, which then runs the code, producing some fancy graphics.One ancient computer serving data to another ancient computer.This setup was constructed, and all code (of mine) written and debugged in the ~20 hours immediately following the formal Hackfest entry deadline. *sigh*Thanks to Tom Greene for the help on the Applesoft HELLO loader code.

Compact Flash storage upgrade for a DECpc 433 - #DOSCember Josh Malone 2020-12-24 | Join me for a #DOSCember journey. Watch me make just about every conceivable mistake upgrading this ca. 1994 486sx laptop to a compact flash hard drive. I mean - you'd think I'd never worked on a DOS PC before! *sheesh*I replace the original Seagate 2.5" IDE HDD with a 512MB CF card by cloning the original drive... eventually, anyway. Along the way, look at hard drive addressing, and the anatomy of an MS-DOS boot volume.

How to (and how NOT to) bootstrap a Tandy Portable Disk Drive Josh Malone 2020-06-28 | A quick video I shot detailing the various failure modes you might encounter when trying to bootstrap a Tandy Portable Disk Drive (TPDD) without TS-DOS.The TPDD is a mass storage device for the Tandy TRS-80 Model 100 portable computer (as well as the 102 and 200). It connects via the serial port using a special cable. The Model 100 doesn't have a built-in driver to access the TPDD, so you need to "bootstrap" the driver from the provided utility disk using a BASIC program and the mode switches on the bottom of the drive.NOTE: This procedure is for the TPDD 1 only -- the TPDD 2 uses a different procedure.
Tandy 102 (Paladin MC-1) memory battery replacement Josh Malone 2020-05-10 | A quick video detailing the battery replacement process on a Tandy 102 portable computer. This machine is actually re-badged as a Paladin MC-1 -- Due to the Tandy 100/102's power and portability, it was often used as an embedded computer inside other specialty equipment. We also take a close-up look at a non-Tandy Option ROM module and its flexible PCB.We disassemble the unit, remove the old battery, do a bit of corrosion clean-up, install the new battery, and run some basic tests.For Tandy 100 parts, including memory batteries, visit arcadeshopper.com(I'm not affiliated w/ this site - Greg is just awesome!)Music: Above The Clouds by | e s c p | escp-music.bandcamp.comMusic promoted by free-stock-music.comCreative Commons Attribution 3.0 Unported Licensecreativecommons.org/licenses/by/3.0/deed.en_USPaladin MC-1 info: worthpoint.com/worthopedia/vintage-paladin-mc-sonic-blueprint-1895753534
Diagnosing and repairing a dead Tandy TRS-80 Model 100 portable computer Josh Malone 2020-01-29 | In this video, I resurrect a very dead Tandy TRS-80 Model 100 portable computer. I arranged a trade at Tandy Assembly 2019 -- a CoCo2 w/ CoCoVGA, in exchange for some repairs, and this is the last of those. This machine showed almost no signs of life when I tested it at the show, so it definitely needed to go on the bench.I check the power supply, the address/data bus, and the CPU clock input until I discover the culprit -- a faulty clock crystal. Then, I replace the memory battery, and run some basic tests, including testing the serial port. I also quickly show loading and running the original PCSG Super ROM.This is the first of what I hope to be a regular repair series. I'm still getting my production feet under me, so please pardon some of the framing and focus issues. Please feel free to ask questions about the process. Also, you can find me on Twitter @48kRAMTools used, include: * Iron: Hakko 936 at 320 - 350C * Tip: T18-K clone * Vacuum desoldering gun: ZD-985 at ~330C * Scope: Rigol DS1052D * Multimeter: Extech EX-330 * Solder: Chipquik SMDSW .020 63/37 * Flux: MG Chemical 8341 paste * T-shirt: @MindFlareRetro

PLATOTerm Amiga 0.3 demo Josh Malone 2018-12-27 | Just a quick session of me connecting to Irata.online using PLATOTerm 0.3 for Amiga. Running on my Amiga 3000 from hard drive. Sorry for the off-the-cuff narration. And a third of the clip is just me typing a note into the system. But, you get the idea of how PLATO works with Irata.online.I also need a better editing workflow / software so I can upload in native 640x480. Oh well... next time!
