Original Blueprint Block Diagrams of the “Steering Wheel” of the First Commercially Available Digital Computer, the UNIVAC I
Three items, as follows.
(1) (Untitled Blueprint) of the Schematics of the Main Computer and Supervisory Control Panel of the UNIVAC I. 18X24 inches. Printed in purple on off-white paper, Undated, ca. 1950-1955.
Condition: the blueprint has eight old folds from when it had been quarter-folded many years ago. There is some amount of yellowing and some browning along fold lines. The sheet of paper itself is still strong and far from brittle. An old two-inch tear has been repaired on the reverse with acid-free Japanese tissue adhesive. In general, this is a better-than-Good item, conservatively speaking.
(2) (Untitled Blueprint) of the Supervisory Control Panel for the UNIVAC.
18x24 inches. Printed in brown(ish) ink on off-white paper. Undated, ca. 1950-1955.
Condition very similar to the item above.
The blueprint shows the entire schematic for the supervisory control panel, a unit which in effect controlled the computer (which was an assembly of units some of which could be operated independently of the SCP).
UNIVAC Computer System
"The first commercially available electronic computer, UNIVAC I, was also the first computer to handle both numeric and textual information. Designed by John Presper Eckert, Jr., and John Mauchly, whose corporation subsequently passed to Remington Rand, the implementation of the machine marked the beginning of the computer era. Here, a UNIVAC computer is shown in action. The central computer is in the background, and in the foreground is the supervisory control panel. Remington Rand delivered the first UNIVAC machine to the U.S. Bureau of Census in 1951."--
