Please find below some information to make your own multi-games cartridge for your Intellevision console : You can find all the details on the original author site : Aotta's github In order to build your PCB you will need the following gerber files : gerber In that version (alpha) you need to patch the PCB are visible on the picture, to ground one of the pin of the cartridge. Here is the BOM : - Two standards leds : D1 : LED (power on) D2 : LED (status) - Resistances : R1 : 220 ohms R2 : 220 ohms R3 : 1k ohms R4 : 1k ohms - Capacitance (104) C1 : 100nF C2 : 100nF C3 : 100nF - Push buttons 4Pin 6x6x5mm SW1 & SW2 : switch - Integrated Circuits : U1,U2,U3 : 74LVC245 (Dip 20) Teensy 4.1 (Look at thepihut.com to find affordable version) - Led screen : Oled Module 0.91" (For Arduino) - Support : For the Teensy & Led screen Once everything is soldered on the PCB, you will need to program the Teensy 4.1 using IDE softare for arduino. You may have to install missing libraries and device components for the Teensy 4.1 You can then use my own version of the software, adapted for the Secam (french) console : https://github.com/zx81zx81/RTO-Cart-secam/blob/main/RTOCart/RTOCart.ino The remaining complex step is to writea .cfg file corresponding for each game you install on the SD card. All games that required the ECS are not supported. Enjoy, Zx Wednesday, January 1. 2020[NEW BATCH] ColecoVision 31-in-1 Flash CartridgeHi all,
Few years ago, with my good friend Buzz, we had launched the production of few pcbs for the Colecovision 31in1. This card contains up to 31 games of your choice (flashed in eprom 27C080) and works directly with your Colecovision console : The price is set to 35 euros (via paypal) and it includes : - the pcb card of the 31in1 - eprom 27C080 programmed and installed on the pcb with 31 games of your choice - custom background and text menu for the loader - shipping fees for Europe There are 5 cards remaining today ! If you are interested please drop me an email (zx81.zx81(at)gmail.com), Enjoy, Buzz & Zx Friday, September 11. 2015CPC464 : How to mod your DDI-1 / CPC 464 to work with a HxC floppy emulatorHi Folks,
I finally succeed to get a SD Slim HxC Floppy emulator to work with my amstrad CPC 464 connected to a floppy drive FD-1. Here is step by step what i did. First of all you need to mod you FD-1 to get the ground and the 5v cable for the HxC Slim SD board. You need to open the FD-1, and to connect the ground and the 5v of the floppy Molex as shown on the picture. Be careful, the 5v is the orange cable in the FD-1 (Red is 12v !). Here is FD-1 back. Then you have to put two jumpers on the ribbon of the DDI-1, as shown below. (Update from Bryce on CPCWiki : The ready jumper is not mandatory with the HxC) You have to cut the two plastic protections as shown on the picture. Otherwise you won't be able to plug correctly the ribbon with the HxC connector. Here is the connections with both 5v molex + floppy ribbon : Next, You have to setup properly the jumpers on the HxC (i gave many tries, and that is the one that worked for me). Of course you have to upgrade the firmware of the HxC, setup the memory card accordingly etc ... (See HxC website, there are tons of documents available there). Finally i got HxC menu working (run"hxc) and also Sorcery game installed on my SD card : Hope that helps, Zx PS: Thanks to Bryce for the updates Sunday, October 5. 2014Video Mod for Intellivsion Secam consoleHi all, I would like the share with a video modification i realized recently for the Intellivsion console (SECAM version). It lets you to connect your console to a TV using a standard RCA/composite cable. The photo above shows where to connect wires on the daughter board (SECAM version), and below you get the schematic to use for this video modification. Cheers, Zx Wednesday, October 1. 2014FFin1 : Cartridge of 255 games for Atari 7800 and 2600Hi All, With my good friend Buzz, we have designed a cartridge with 255 games for the Atari 2600 and 7800. Here is the schematic if you want to realize your own version : on buzz web site. You will find here, an archive with the binary image to be flashed on the eeprom 27C801, but also the code source of the loader. This "loader" is based on the "A text adventure game/engine for the Atari 2600" developed a while ago by Greg Troutman in 1997. Archive of the ffin1 loader.

Wednesday, August 14. 2013PSX adapter for megadrive v2Hi, Here is a picture of the new version (a bit less ugly than the prototype) For very few euros you can build your own. I used MPlab for the development and MiniPro for PIC programming. All the schematics and source code, hex files and all informations are here. Enjoy, Zx Sunday, June 30. 2013PSX adapter for megadriveHi All, One of the best old console for shoot'em up is the megadrive (after PCE engine of course ). I wanted to use a PSX arcade pad with a megadrive, so i decided to build this adapter. This version is a derivative version of the work of Thomas Kirk (many thanks to him) who did it for atari and amiga db9 joystick. You need a few set of components : - PIC16F819 - 2 LEDs (optional) - 3 resistors - 1 DB9 female - 1 PSX female connector (i used an extention cable for PSX). Here is my ugly prototype : And for a few bucks you can build you own. I used the MPlab software for PIC development and MiniPro to program the PIC. All schematics, asm and hex files, plus any required informations to build your own adapter are here Enjoy, Zx Sunday, February 17. 2013ColecoVision 63-in-1 Flash CartridgeHi all, With my good friend Buzz, we spent last past few weeks on a new project called "63 in 1".
