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). The 1110 CAU expanded the memory address range from the 18-bits (1108 and 1106) to 24-bits, allowing for up to 16 million words of addressable memory. The core memory used on the 1108/1106 systems was replaced with faster plated wire memory. Each memory cabinet contained eight independent 8K plated wire memory modules, or 64K for the entire cabinet. As with the 1108/1106, there was a maximum of four 64K cabinets per system. The 1110 also had 'Extended Memory' cabinets accessible in a 'daisy chain' arrangement to augment main storage. It was possible to utilize the 1108 64K core memory cabinets as Extended Storage, but in most systems utilized, the larger, less expensive 131K memory cabinets from the 1106 system. Up to eight Extended Memory cabinets were allowed, for a maximum of one million words of Extended Storage. An ESC (Extended Storage Controller) was required for each pair of memory cabinets to provide the physical connection, and address translation, from the 1110 CAUs and IOAU(s).
