Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The UNIVAC LARC (Livermore Advanced Research Computer) was Remington Rand's first attempt at building a supercomputer. It was designed for multiprocessing with 2 CPUs (called Computers) and an Input/output (I/O) Processor (called the Processor). However both machines only had one Computer, so no multiprocessor LARCs were ever built. The LARC was a decimal mainframe computer with 48 bits per word. It used bi-quinary coded decimal arithmetic with 4 bits per digit, allowing 11-digit signed numbers. Instructions were 48 bits long, one per word. Every digit in the machine had one parity bit, for error checking, meaning every word occupied 60 bits (48 bits for data with 12 bits for parity check). The basic configuration had 26 general purpose registers and could be expanded to 99 general purpose registers. The general purpose registers had an access time of one microsecond.
