We like to keep a keen eye open for interesting projects that may not have had much exposure. Today is no exception as bring you two teams that have some cool prototypes up and running.

The prototype Yellowstone card in action.

First we bring you the Yellowstone prototype Apple Disk controller. One thing that has always frustrated Apple II owners is the vast variety of disk controllers that were made for the system over its long life. The Yellowstone project is an attempt to use a modern FPGA based card to emulate all of these controllers. Just recently the team have succeeded in creating a clone of the Liron card and successfully booting from it. This milestone opens the way for a universal floppy controller for the system. Whilst not yet a real product, this is one to watch for all Apple II owners.

HD Retrovision’s prototype cable.

The second project we wanted to highlight was the excellent work being done over at HD Retrovison to develop a YPbPr cable for the Dreamcast. The team have a prototype cable working that can support not only the normal video modes but also supports 480p. As modern TV’s are starting to drop the old VGA connector, having another way to be able to pipe a high-resolution signal in is fantastic news. Follow the progress on their website HD Retrovision.

480p goodness from the Dreamcast.
