Jeffledger wrote this Instructable detailing his construction of a retro-style microcomputer using a Parallax Propeller Multicore Startup Special dev kit (any Propeller board should work), an RCA Ultimate TV IR keyboard, 38 kHz IR receiver module, resistor and micro SD card with adapter.
The result is a mockup of a retro computer on which you can write programs, play games and music just like back in the day. The Propeller runs Jeff’s PropDOS in EEPROM, and he promises to release many additional retro style programs to run on this machine.
