Datanetics Rev B Keyboard PCB (Modern)

Build your own reproduction Datanetics Rev B keyboard with this PCB. This keyboard can be used directly with the Apple-1 computer or for any other purpose where a parallel ASCII keyboard is required.
 
This PCB is designed for modern key switches and has all original bugs fixed. It also uses the modern ATMega644P microcontroller instead of the hard-to-find MM5740 encoder. If you're interested in the original version of this PCB, please see this listing.
