Atari 2600 games on Baffa-2 Project

Description

"Baffatari" is the codename for the Baffa Atari 2600 board that allows you to run atari games on a computer with a 6502 CPU. It is currently part of the setup that allows the Baffa-2 to run programs like an Apple-1.

Baffa-2 is an educational and personal project with the aim of understanding how computers work through 80's 8-bit commercial machine designs. It has a modular concept with boards that can be combined to develop your own design and configuration.

Details

Baffa-6502 is a subproject of Baffa-2 to create a new series of boards around the 6502 CPU architecture. This allows a new group of retro computers to explore in my project.

The first "setup" is an Apple -1 that runs Atari 2600 games (like CP/M that runs Colecovision) and is still in development. For now, I was able to test the new Atari 2600 card for the Baffa-6502 (Codename "Baffatari" 2600)

I have been designing several PCBs for the Baffa-2 Homebrew Microcomputer project and I have received great support from PCBWay to continue advancing these projects with 8-bit computer compatible modules.

In March, I had thought about taking a break from the project and that's when I was offered PCBWay support for my project. I couldn't even imagine the possibility of getting such support, even knowing that PCBWay sponsors and supports many projects in the Retro community. The Baffa-2 was still a small project and this support made it possible to speed up the production of several boards that I had already designed but that I could not imagine when I would be able to test them.

A few days ago, I received the latest set of PCBs under PCBWay's sponsorship. They helped me to finalize what I had designed for the Baffa-6502/Baffatari - Apple-1 compatible computer that is capable of running Atari 2600 games. I am very happy to be able to present this project results and I would not have been able to finish it without the sponsorship of PCBWay.

Thanks PCBWay for your support https://www.pcbway.com/

PCBs in the box... what are they?

The production and delivery of the boards was very fast.

Loading Games from Cartridge or SDCard

For now, I can load games only by listing (hex code) via terminal, but I've designed two ways to load games on my apple-1 replica/baffatari.

If you have an Unocart or old cartridges, you can use the backplane's peripheral port to attach a cartridge expansion. This allows you to run games directly from the cartridge.

But, there is the option to load the games via SDCARD... The SDCard board is based on P-LAB's "Apple-1 microSD storage card".

Both boards will be available soon... Can't wait to post videos showing them working :)
