We us a hardware clone (see below) of said machine to control the nuclear reactors and the associated boilers and valves at the Bruce "A" and Bruce "B" Power Generating Stations. They are opperated by Bruce Power.

Some parts have been replaced with more modern components. For example, the core memory has been replaced, but it still only has 32KW (64KB, 16 bit addressable) of RAM. We load binaries on the machine via a serial connection to a device pretending to be a paper tape reader to the Varian.
