3081 Processor Complex The 3081 Processor Complex, which was announced in 1980, provided internal performance about twice that of an IBM 3033 Processor while significantly reducing space, cooling and power requirements. The 3081 used a unique dual processing scheme and new logic modules. Shown here in a design model, the 3081 provided up to 24 channels, or paths for the transfer of data, and a maximum main storage capacity of 32 million characters.
