 Single Level store Hmm.   Over 25 years old?


 38 [1]
       The System/38 midrange computer was rolled out in October 1978 with many
       advanced features. These include a single-level store, object-oriented
       addressing and a high-level machine interface to the user. The System/38
       had been designed to facilitate terminal-oriented, transaction-driven
       operations and to improve programmer productivity.

                     The basic system included a central processing unit with
                     main storage ranging between 524,288 and 1.572 million
                     positions, 64.5 to 387.1 million positions of disk storage,
                     a console keyboard/display, a diskette magazine drive and
                     work station controllers for up to 40 directly attached IBM
                     5250 Information Display System devices. Depending on
                     processor model, main storage cycle times were 600 or 1,100
                     billionths of a second.

                     The purchase price for a complete System/38 at announcement
                     was $91,780. Deliveries of the product began in August 
1979,
                     and some models of the System/38 were withdrawn from
                     marketing between March 1982 and June 1986.
