This is a clone of the SwiftLink RS232 cartridge using the v2.0 schematics with gold contacts. This is a high speed RS232 device that contains a 6551 ACIA that allows error-free communication at up to 38,400 bps. It works with the cartridge port of your Commodore 64 and 128. This has been proven to work on all software written for it’s use including C*Base BBS. This board is created, assembled and tested by our good friend DMackey828 with all new components.
