Updated: 04/26/2017 by Computer Hope
The Unibus was an early computer bus technology used by Digital Equipment Corporation's VAX (virtual address extension) and PDP-11 computers. It was created in 1969 by Gordon Bell and Harold MacFarland at Carnegie Mellon University. It could address a maximum of 256 kibibytes of memory, in addition to being an asynchronous bus; meaning it could accommodate devices of varying clock speeds.
