Dubbed a Software Defined Computer, the Propeddle is a new forthcoming computer kit that has a 65C02 processor as well as a Propeller CPU, and is planned to be able to emulate various 6502-based computers by changing the software. The prototype is already able to emulate an Apple 1.
The name Propeddle comes from the Propeller CPU used on the board, and Chuck Peddle, one of the designers of the 6502 microprocessor.
It has similarities to the Briel Replica 1, but aims to be able to be able to emulate different computers.
It looks like a interesting project, and one that I will keep my eye on. Being able to emulate a number of different old computers would be cool. It should be able to emulate, say, a KIM-1, Commodore PET, or Ohio Scientific Challenger by changing the firware. I wonder if it will have the processing power to emulate a more complex machine like the Apple II?
