• Baffa-81: Running ZX81 on Baffa-2 Homebrew Computer

  Augusto Baffa • 11/27/2022 at 16:08 • 0 comments

  After all, I had to create a set of boards to clone my beloved first Sinclair ZX81 computer. Using the Baffa-2's CPU and Dual Clock board, it is possible to add 3 more boards to provide 32KB Ram/Rom, Keyboard and Cassette and Video I/O to build a ZX81 Clone.

  In this photo, the Baffa-81 is using the new Baffa-2 backplane lite which has only 6 slots (original has 12 slots). This option was created because it is cheaper and can be used on smaller sets of boards.

• Baffa-2 ZX81 Boards on its way!

  Baffa-81 is a Sinclar ZX81 clone on Baffa-2 Homebrew Computer. It's based on Grant Searle's ZX80/81 Project and Wilco's ZX80/81 board. Also, the ps/2 interface is based on Danjovic's Tek v2 project.

  All boards have arrived! Now I need to have some time to assemble and test them. I would like to thank PCBWay again for all their support on the Baffa-2 project. In addition to the boards being great (excellent quality), manufacturing and delivery are very fast.

  Projected boards:

  I had also created a reduced version of my backplane to reduce costs of this project :) . It's half the original backplane with only 6 slots. Can be connected to others via expansion port.

  To complete the setup, it is necessary to use the Z80 CPU board and the dual clock board.
  

• Baffa-X: MSX1 Compatible Computer tested!

  Baffa-X is a project to transform Baffa-2 into a MSX1 Computer. It's based on Brazilian Sharp's HB-8000 (Hotbit) schematics and Beer 202 IDE Board. The projects also uses the original Z80 CPU, 64KB RAM and TMS9918 Boards from Baffa-2.

• Apple-1 Running on Baffa-2

  Augusto Baffa • 06/28/2022 at 06:05 • 0 comments

  I've just tested a new set of boards for using the 6502 CPU. The project is slightly inspired by the RC6502 and I believe it may collaborate with it in the future. Initially it is a simple 6502 computer that is capable of running the Apple-1 rom but it should evolve soon.

• Baffa-6502 plays Atari 2600 games

  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)
