The TriBladeProp is a Single Board Computer (SBC) based on three Parallax Propeller microprocessor chips. Each Propeller microprocessor contains 8 RISC microprocessor cores on the one chip (see https://www.parallax.com/microcontrollers/propeller).
Features include SRAM, Flash, microSD, VGA, composite video (TV), PS2 Keyboard and Mouse, power regulators and USB interface to PC.
One Propeller does the procesing with extra SRAM (512KB/1MB of static RAM memory), and a microSD socket for up to 2GB 8GB of external memory.
Emulation of popular "retro" computers may be run on this chip. A Z80 emulation (called ZiCog) runs CP/M 2.2 on this chip.
The second Propeller acts as a terminal with VGA and/or composite video (TV) outputs and PS2 style connectors for Keyboard and Mouse.
The third Propeller provides additional I/O for interfacing to external boards.
