  • Flashback Project: SOCZ80 FPGA Retro Computer

    Here’s a really great Papilio project that we wanted to revisit: The SOCZ80 Retro Computer! Here is some more info: I built a small FPGA microcomputer for the Papilio Pro board. I’ve ported a few operating systems to run on it. These 8-bit machines have very minimal features but (somewhat unexpectedly) I found they can run a multi-user, multi-tasking…

  • Papilio Projects: Chord Keypad to control CAD software

    Here is a project that we missed from a couple years ago. A chord keypad that is used to speed up PCB development by making common key strokes easily available. This is particularly useful for EAGLE PCB development where you are continuously typing in commands on the keyboard…   Our friend Ken Boak put together…

  • Tetris-like game for the Papilio and Arcade Megawing

    Sometris is a Tetris-like game that Papilio user Peter Ivanov has written for the Papilio One and Arcade MegaWing, the game works with DesignLab 1.0.8. This is a tetris-like game for Papilio One 500K + Aracade Megawing. You need a VGA monitor and optionally a Atari/Commodore compatible joystick. I’ve used Papilio DesignLab 1.0.8. The source…

  • Robots Game Implemented On The Papilio!

    Inspired by the snake game our forum member Jaxartes has successfully managed  to implement the Robots game on the Papilio Pro with the Arcade MegaWing using Verilog, his source code should be able to run on other FPGA platforms with comparable capacity. It displays in 1024×768 on a VGA monitor, and is controlled by keyboard.  Or,…

  • Get your 3D case design for Papilio Logic Analyzer over at Thingiverse

    Papilio user Larry McGovern just posted this beautiful design for a 3D printed case that turns your Papilio Logic Analyzer into a sleek device. Here is the original Forum Post. Here is the Thingiverse Link.          

  • MULTICOMP Z80 CP/M migrated to the Papilio Duo Platform!

      Hello Papilio fans today we got an awesome project to share with you! Our forum member jlcollado has managed to migrate the Grant Searle’s brillant work called MULTICOMP to the Papilio DUO, the final result is a very usable and complete Z80 soft-core based machine, running the venerable Digital Research CP/M 2.2 OS. I’ve built the Z80 CP/M variant, complete with VGA & Keyboard…

  • Snake Game Created With The Minimum FPGA Resources!

    Hello FPGA and Arcade games fans! A couple of weeks ago we posted about how to play the Snake game on your FPGA in fore easy steps, our community member mkarlsson was not totally satisfied with the amount of FPGA resources the Verilog code uses and decided to rewrite the game to make it use less…

  • Are we witnessing the birth of the Gameduino 3?

    Over in the forums Ken Boak, James Bowman, and myself have been playing with a prototype shield (codename Evita) using the EVE FT812 chip and the Papilio DUO. Ken developed a nice board and James has been able to overclock the thing to output a nice crisp 1024×768 resolution through a VGA connector. Things have been coming…
