Comments

As a self-contained system the Superbrain could feasibly be moved from office to office.
Was clearly aimed at the top end of the business market and CP/M applications including wordprocessing, spreadsheets, inventory, accounting etc. were available.
Intertec (later called Wells American Corporation) went on to make Intel 8086-based computers and, from the mid 1980s, fully IBM compatible 80286 and 80386 machines.
