Description

Based on EDVAC, SEAC acclimated alone 747 exhaustion tubes (a baby cardinal for the time) eventually broadcast to 1500 tubes. It had 10,500 germanium diodes which performed all of the argumentation functions. They were broadcast to 16,000. It was the aboriginal computer to do all of its argumentation with solid-state devices. The tubes were acclimated alone for accession and/or inversion. The apparatus acclimated 64 acoustic adjournment curve to abundance 512 words of memory, with anniversary chat actuality 45 $.25 in size. The alarm amount was kept low (1 MHz).

The computer's apprenticeship set consisted of alone eleven types of instructions: fixed-point addition, subtraction, multiplication, and division; comparison, and ascribe & achievement eventually broadcast to 16.

The accession time was 864 microseconds and the multiplication time was 2980 microseconds (i.e. abutting to 3 milliseconds).
