1108 Multi-Processor System The UNIVAC 1108 was the second member of Sperry Rand's UNIVAC 1100 series of computers, introduced in 1964. Integrated circuits replaced the thin film memory that the UNIVAC 1107 used for register storage. Smaller and faster cores, compared to the 1107, were used for main memory. In addition to faster components, two significant design improvements were incorporated: base registers and additional hardware instructions. The two 18-bit base registers (one for instruction storage and one for data storage) permitted dynamic relocation: as a program got swapped in and out of main memory, its instructions and data could be placed anywhere each time it got reloaded. The additional hardware instructions included double precision arithmetic, double word load, store, and comparison instructions. The processor could have up to 16 input/output channels for peripherals. We are extremely grateful to both Dawn and Kim Wakefield for the kind donation of the collection of their late father Richard Wakefield
