7800 - Why didn't this already exist?

Just a quick experiment I worked out last night using some additional logic wired into the 7800 so that remote pause can be a thing if you have a controller that is configured to match.

M.O.D.E. - Power LED as Access light - DC

Did a really quick little project last night. I'd been kicking this around in my head but decided to try it finally last night. The M.O.D.E. or Multi-Optical-Disc-Emulator from TerraOnion has a nifty set of additional pins along one side of it for adding in additional features. Among them are the ability to add in a wire for adding a physical reset button or button to simulate a Disc Swap process etc. One of the extra pins is for wiring in an additional LED in the system somewhere that is direct

Even working PSUs are ticking timebombs

Not a video to share this time, although in hindsight I should have made one as a quick tech video. But recently I decided I would get some replacement filter caps for use in standard wall wart power supplies like those used with our Atari, Sega, etc. consoles from back in the day. As I have quite a few of them on hand and wanted to test them out I decided to start with a few Sega Genesis power supplies. I decided to look at three different supplies last night. I first checked the voltages from

Complete Roland MT-200 Basic Tutorial and Guide

In this 3 video series, I go over the basics and understanding of the Roland MT-200 sound module. It is an excellent multifunction sound module that can act as both a sequencer and sound module. This means that in addition to being a very nice general MIDI and Sound Canvas sound module, it also has the ability to record MIDI songs from the MIDI in port and save them to diskette to be played back in a standalone fashion later, making it a MIDI Jukebox as well! The first video goes over the basi

Roland MT-200: How to configure, install, and use a GoTEK Floppy Emulator

As some might know by now, I've got an MT-200 that I picked up over a month ago now. Really cool little device from Roland that was originally intended for use in teaching music. But these devices have the ability to play back midi files through built in disk drives that use IBM formatted 3.5 inch disks. They can also be used as sound modules and with modern day computers can still be made to be used with ScummVM and Dosbox for classic gaming. Anyway I was getting frustrated with my disks seemin

BK 1474 O'Scope Introduction

I am only a hobbyist and NOT an electrical engineer. As such I'm sure my terminology and explanations of things will be off or perhaps completely wrong. As such, please let me know in comments on such mistakes as it helps me and all others who might view this video to learn. With that, this is my basic intro to my BK 1474 O'scope that I got some time ago and some ways it can be used. This video is only meant for fun and not as instructional as most of my other videos are. Enjoy!

Intellivision - 2609 - Capacitor Replacement Video

Been doing a few composite AV mods on client intellivisions. Though I would video the process I go through for doing a capacitor replacement. I'm working on trying to get the videos down to be more watchable in smaller amounts of time but perhaps too much compression on time is used in this video?   Big special thanks to Adan Toledo for his permission to feature some of his music from the CollectorVision homebrew release of Sydney Hunter & the Sacred Tribe for the Intellivision!   - Orde

Atari 5200 DC/DC converter.....conversion

Replaced the original 7805 regulators from my atari 5200 recently and installed a pair of DC/DC switching converters in their place. In this video I show the power measurements from the original 7805 and from the DC/DC converters. Next up with be the Intellivision once I get additional parts in.

Sega Master System Voltage Regulator Mod/Upgrade

I've been working with DC to DC buck converters lately on a few of my classic consoles. Here is a detailed video of the process wherein I change out the 7805 voltage regulator on my SMS with a Traco Power DC/DC +5 converter. I show some numbers using my Kill-a-Watt before and after to give an idea on the differences. With the SMS the differences weren't nearly as much as they were with my 7800 that I did this mod to as well. But I didn't video that one and kinda wished I had now. I also explain

A genesis va3 Model 1 with proper DAC possible? Yes...yes it is. But....

So the other night I tackled a hardware upgrade that I had seen mentioned in a youtube video that seemed really interesting. It was a video where a another retro gamer and hardware modder was showing his latest modification using a Yamaha 3438 discreet synth chip to produce the music and sounds in place of the stock Yamaha 2612 that came with the model 1 genesis units. The advantage of doing this was that the 3438 was essentially pin compatible but featured a true 8-bit DAC within it and better

Lynx Model 2 - Capacitor Replacement

Just did a capacitor replacement on my Atari Lynx model 2 this weekend. One of my two units was suffering from some nasty audio clipping, distortion and overall low volume. The camera was on a lower quality shooting mode and I did realize until I was done with the filming. I apologize for that but you can still make out enough to get see the overall process and results afterwards.
