Welcome to the Foenix Project! Here you will find a series of brand new computers lovingly made by Stefany Allaire in the style of the early 8, 16 and 32 bit machines of lore! This is your chance to be a participant in the development of a new platform -- to start with a brand new machine akin to a high-end Atari or Amiga, write its very first programs, see what it can do, push its limits, and experience something new! Models are available with a 65C02 CPU, 65816 CPU, a 680x0 series CPU, or both, with more CPU options planned for the future.

(*): Due to FPGA's availability and abusive cost, those models are presently on hold.

(**): The concept behind the GenX is its ability to support different processors through a modular system.

(***): The WIFI communication is achieved through a ESP32/WIFI (Feather) Type board and it is optional.

(****): The RevA of the board doesn't have an extra 9Pins connector to interface with NES/SNES Adapter.

(^): An external NES/SNES interface box is needed, so this is extra.

(^^): The External SIDs are Sockets only, they must be populated by the owner.

OPM = YM2151, OPN2 = YM2612, PSG = SN76489

Is this another FPGA Retro like the MiSTer?

  • No! These machines are the real thing. You'll be running on a real 65816, 68000, 68040, i486dx2, etc. :).

Are these machines compatible with the C64? C128? Amiga? Atari-ST? IBM-PC?

  • No! This is not a MEGA65, a Vampire, or an Ultimate64. We already have those platforms. This is something new and different!

Is there an emulator?

Is the hardware "Open Source"?

  • The schematics are available for download from the Discord. The FPGA code is presently closed-source to keep the platform from becoming fragmented.

Are there any programming tutorials for the Foenix?

Happy hacking!
