I successfully made an adapter to use the Coco WordPak-RS on a Commodore 64 and also, using the CP/M cartridge you can run a modified CP/M disk to use the WordPAK :) Watch it: https://www.youtube.com/watch?v=XFsHDW1WnaE No WordPak-RS were harmed during this video, and I used my cloned one :) Felipe
