Line 21:

The system as a whole operated in a lock-step fashion, able to perform one floating point instruction per cycle. The system normally ran at 1&nbsp;MHz, so each PE performed about 1&nbsp;MFLOPS, and the system as a whole around 288&nbsp;MFLOPS. The integer instructions were about 100 times faster, with the system as a whole running about 2,880&nbsp;MIPS. This was much faster than any machine of the era.<ref name=pepebook/>

A [[Burroughs B1700]] computer system was used as a test and diagnostic computer. A custom software package, called TRANSET, which executed on the B1700 was used to debug and maintain PEPE's processing elements. Burroughs delivered PEPE to the Ballistic Missile Defense Advanced Technology Center (part of US Army's Strategic Defense Command) in [[Huntsville, Alabama]] in 1976.<ref name=Ford/> Testing was apparently successful, but Bell concluded that the machine was too expensive for the sorts of threats being addressed by the [[Safeguard Program]] that was being deployed in the 1970s.<ref name=silogic/>
