The Lear Siegler ADM-3A terminal is an expanded version of the ADM-3 terminal. It was introduced in July, 1976 at a price of $1045. The ADM-3A added direct cursor addressing.[1] By 1981, the price had been reduced to $595.[2]

A graphics option was available in May, 1982 at a price of $1,050.[3]

The terminal was created by Dennis J. Cagan and 3 other engineers at LSI. In 1975, these engineers left Lear Siegler to form Soroc Technology. The first product from Soroc was a design similar to the ADM-3A, which was sold to Beehive as the Beehive B100 in 1976-1977.[4]
