Hardware Overview

All Foenix systems include a WDC 65C816 CPU @ 14.318Mhz and the following base features:

Graphics Layers Sound Ports
320x240x60fps 16x16 mouse pointer 2x Gideon FPGASID SD Card slot
400x300x60fps 8x8 character plane 16-bit stereo CODEC 2x PS/2 (kbd/mouse)
640x480x60fps 64 16x16x256 sprites TI SN76489 (Sega, Cabinets) Stereo 1/8" headphone
800x600x60fps 4x 16x16x256 tile planes Yamaha OPL3 (Sound Blaster) Stereo RCA Line In/Out
24-bit RGB color space 2x 256-color bitmap planes 3KHz piezo beeper 2.5" internal IDE HDD

Different models within the Foenix range have additional features:

Model CPUs System RAM Video HDMI Ethernet SID sockets RS232 ATARI S/NES C64 OPM OPN MIDI Floppy Parallel
U 1 2MB 2MB 1* Optional* Optional* 1 (3-wire) 2 2*
U+ 1 4MB 2MB 1* Optional* Optional* 1 (3-wire) 2 2*
FMX 1 4MB 4MB 1* Optional* Optional* 2 (9-wire)* 2 2* 2 YM2151 YM6212 in+out 3.5" 1.44 25 pin
GEN-X 2* 8MB + 16MB 8MB 2 Included 2 sockets 2 (9-wire) 2 4 2 JT2151SA JT2612SA in+out 3.5" 1.44 not exposed
  • ∗ The GEN-X can have a second CPU: 68000, 68EC030, 486dx2-66, and more to come.
  • ∗ Each additional CPU in the GEN-X has its own private 4MB of SYSTEM RAM and 4MB of flash.
  • ∗ The EXP-C100-ESID expansion card adds 10/100 Ethernet and two SID sockets to a U, U+, or FMX.
  • ∗ The SNES/NES Joystick Adapter Box for the C256 Foenix FMX converts the two ATARI ports to 2x NES or SNES ports.
  • ∗ The SNES/NES Joystick Adapter Box for the C256 Foenix U/U+ converts the two ATARI ports to 4x NES or SNES ports.
  • ∗ The EXP-C200-EVID expansion card adds 10/100 Ethernet and a second DVI port (text-modes only) to a U, U+, or FMX.
  • ∗ The 8MB of system RAM on the GEN-X is local to the 65816; the additional 16MB of DRAM is available to all CPUs.
  • ∗ The 2nd 9-pin RS232 port on the FMX is available on an internal Intel compatible header.
