• ∗ The GEN-X can have a second CPU: 68000, 68EC030, 486DX-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 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.

Early Software

You will need to reset (or even power cycle) the Foenix between uploads to clear the memory and restore the default configuration. These are early days!
