The Dragon's Claw
From The Dragon Archive
The Dragon's Claw is an extension cartridge for the Dragon by Lucidata.
It features two parallel I/O ports. One with the BBC User Port pinout, and the second one with a Centronics Printer Port pinout.
The cartridge also allows connecting another cartridge like a disk controller, and up to 4 Dragon Claws.
The heart of the Dragon's Clay is the Rockwell 6522 VIA (Versatile Interface Adaptor) chip.
