TX-2
From Computer History Wiki
The TX-2 was an early transistor computer; it was a follow-on to the ground-breaking TX-0 at the MIT Lincoln Laboratory.
The TX-2's magnetic tape mass storage system, created by Tom Stockebrand, used 1/2" tape, but was block addressable, unlike most magnetic tape systems, which could only write sequentially. He later moved to the LINC project, along with several other TX-2 alumni, where he helped create the descendant LINC tape system; he then moved to DEC, where he helped create DECtape, very similar to LINCtape.
Beginning in 1964 a timesharing system called APEX was put together on the TX-2 computer at Lincoln Lab under the guidance of Larry Roberts using a small number of consoles with graphics capability.
