Single Board Computer using multiple Parallax Propeller Microprocessor chips
Cluso's TriBladeProp PCB
The TriBladeProp is a Single Board Computer (SBC) based on three Parallax Propeller microprocessor chips. Each Propeller microprocessor contains 8 RISC microprocessors on the one chip (see www.parallax.com). 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/4MB of static RAM memory), up to 8MB of Flash memory, and a microSD socket for up to 2GB of external memory. 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.
Emulation of other older popular "retro" computers may be done on the TriBladeProp board. A Z80 version running CP/M is in the advanced stages.
The board has been designed to be assembled by the hobbyist and is based on all through-hole components except the FT232RL and microSD connector. The FT232RL is used in the on-board PropPlug to communicate with a PC - an external PropPlug can be purchased preassembled. The microSD connector is fairly easy to solder with a small tip soldering iron.

The TriBladeProp bare PCB is available for US$30.00 plus US$4.50 postage (unregistered/uninsured AirMail) plus any applicable taxes from firstname.lastname@example.org Payment by PayPal.
Multiple TriBladeProp PCBs can be purchased in panels of up to 5 PCBs. Jumpers can be used to connect the power rails together. Alternately, single PCBS can be stacked.
I can solder the surface mount parts for a small fee. If there is sufficient demand, I may stock a kit of components.
See the Parallax Forums for further discussion on these pcbs...
The SixBladeProp PC was designed to use 6 Parallax Propeller Microprocessor chips. It has been replaced with the more functional TriBladeProp PCB, which can be stacked, or be purchased in panels of up to 5 TriBladeProp PCBs.
