The C256 GEN X Family
The GEN X is a multi-CPU capable new-retro computer that sits at the intersection of the C256 WDC 65816 Foenix family of systems, and optionally, the growing A2560 Motorola 68k family of systems.
With the WDC 65816 component-set embedded on the main board, every GEN X is equipped to run the growing library of FMX and C256U and U+ games and programs.
With the add-on of a MC680x0 processor (or an Intel i486/DX2 if you choose), you can harness a secondary power-up mode. Capabilities are identical across the board; the same VICKY dual head core graphics engine with FPGA embedded instances of classic audio ICs, access to all of the same ports and peripherals as well.
The GEN X offers 3 form factors, beginning with the ‘Cube’ (right hand side above), in its 11″ x 11″ x 11″ enclosure. The Cube comes complete with a floppy drive, an internal power supply, and a full complement of audio ICs, the GEN X cube has everything included except for a pair of SID ICs; (sockets are panned ‘left’ and ‘right’; use your own hard to come by MOS ICs or pick up one of the available clones).
Importantly, every GEN X model has two FPGA based Gideon SID instances in addition to a plethora of Yamaha and more; this is key for game and application developers because every GEN X model has all of the ICs represented within the Altera FPGA.
Next up is the ‘Lunch Box’ (LB) that you see on display (above). This is the first public showing of the unit and it is very much cube-like occupying the same 11″ x 11″ footprint, except the LB is 1/2 height, or 5.5″. Absent is the floppy and some of the physical audio ICs, but otherwise, it is functionally identical to the Cube, same ports, memory, etc.
Finally, there is the ‘Pizza Box’ (PB). Similar to the Lunch Box, except less expensive still, and smaller (< 2.5″ tall). You’ll notice that the distinctive stereo speakers are no longer onboard, nor are direct connect NES/SNES game ports (however, the Pizza Box does host 4 x Atari Joystick connections, two of which can host analog paddles or an external break-out box for NES / SNES controller connectivity).
Most significant, and common across the line is the fact that all GEN X models have DIN MIDI in and out, a quad package version of the WDC 65816 running at the full 14 MHz, and a slot for a 2nd CPU which can be selected at boot time based on the position of a pushbutton toggle switch which is located on the front of the unit.
Secondary CPUs may be the Motorola 68SEC000 @ 20 MHz., a 68040 running at 25 MHz., or an Intel 486/DX2, with a RISC V core under consideration. Our display shows the Motorola MC68SE000 (left) and an Intel i486/DX2 (right).
