The crew from the German HIVE Project are developing a retro style DIY computer with Parallax Propeller chips. The design includes three Propeller chips (containing a total of 24 RISC processors), VGA graphics, video output, stereo sound, about 1 MB of RAM, SD Card reader, LAN, mouse and keyboard. The design uses all DIP and through hole components.
The original project site (in German) contains full details on the project. The page translated into English by Google can be accessed here. The project is open source and is well documented (see the Downloads link on their site for hardware and software files.)
A comprehensive project by a dedicated crew. If you’re into retrocomputing or Propeller dev, you’ll want to check this out.
