in order to differentiate themselves from the numerous models in this performance range, the fp-6000 would directly support multitasking, then known as "multiprogramming", as well as be highly modular. the prototype machine was completed in 1962, and was delivered to the frb in early 1963. further sales proved difficult however. one was purchased by the drb's station in dartmouth, nova scotia, another by the toronto stock exchange , one by saskatchewan power, and a final machine by a research facility in dalkeith, bringing the total to five sales.
