VIC-REL by Handic SoftwareRelay Cartridge for the Commodore 64/128
Have you ever thought "Why can't I use my Commodore 64 to control the lights while I'm on holiday?". Now you can simply run a little program that controls the relays provided by the new VIC-REL cartridge.
Your imagination is the only limit for the applications possible: control of robot arms, burglar alarms, garage doors, door locks, electric radiators, lamps, transmitters, fish tank lights, remote control toys, pumps, telephones, miniature railways and much much more.
The VIC-REL Cartridge is connected to the User-Port and has 6 Output Relays (connections 1 to 12), a +5v DC (connection 14) and +12v DC (connection 15) and 2 Inputs (connections 17 to 20). These are controlled through locations 56577 & 56579
