Univac 1110

The UNIVAC 1110 was the fourth member of Sperry Rand's UNIVAC 1100 series of computers, introduced in 1972.

The UNIVAC 1110 had enhanced multiprocessing support: sixteen-way memory access allowed up to six CAUs (Command Arithmetic Unit, the new name for CPU and so called because the CAU no longer had any I/O capability) and four IOAUs (Input Output Access Units, the name for separate units which performed the I/O channel programs). It also had 'extended memory' cabinets accessible in a 'daisy chain' arrangement to augment main storage. The larger configurations, 6x4+ were used by NASA. It also introduced an extension to the instruction set, of 'Byte Instructions'.

When Sperry Rand replaced the plated wire memory with semiconductor memory, the same machine was released as the UNIVAC 1100/40. In this new naming convention, the final digit represented the number of CPUs (called CAUs) in the system.

Sperry Rand sold a total of 290 processors in 1110 systems.
