CardCo started as manufacturer and distributor of C64 and VIC20 peripherals; for the Amiga series, only aMEGA and a SCSI interface was produced.

The company went out of business in 1986, as the C64 market became less profitable and a reorganization was necessary to better serve the needs of the faster moving Amiga market - so Ed J. Lippert II took the two Amiga expansions (the expansions in development as well) and formed C-Ltd. Supra bought out the rights to manufacture the remaining CardCo C64 expansions.
