What was the physically smallest Cray machine ?
The smallest, commercially available machine, was the EL92 a repackaged version of the air cooled EL range which measured approx. 1.2m high by 0.6m wide by 0.6m deep and could run from a normal power outlet. Whilst not a big commercial success as it was a bit late to market, it was widely used for trade shows, software development and as loan equipment. Available in 2 and 4 CPU versions with 512Mb memory it was truly a deskside Cray. Good write up and pictorial in “Advanced systems” magazine July 1994.
