Description
The 2100A replaced the 2116, 2115 and 2114 in 1971. The 2100A was compatible with the earlier computers and used the same I/O boards. It was the industry's first microprogrammable minicomputer.
The 2100A included an integrated power supply and came with 14 I/O channels within the mainframe (externally expandable to 45 channels). The power supply was auto-switching between 115V and 230V (the first in a minicomputer).
