A USB-based Dragon I/O board with Dragon joystick ports, keyboard port, tape port, cartridge slot, serial port, parallel port!
Just plug it in to a nano-ITX board, and you'll have a "complete" software upgradable Dragon!
Could be mounted in cases from broken Dragons!
Any engineers/techs here? Would it be possible that some of the features of this CoCo board would work with dragon peripherals as well?
