    Lincoln Test-Experimental 
    Computer Model 0 

Considered offsprings of the 
Whirlwind computer, the TX-0 (on 
display on the mezzanine) and 
the TX-2 computers were among 
the most advanced machines of 
their time.  TX-0 was developed at 
Lincoln Laboratory by some of the 
members of the Whirlwind development 
team. It was designed to 
verify that a 64 Kword core memory
could be built and to test out 
a new type of transistor circuitry,
using the Philco SBT100. Surface 
barrier transistors costing $80. 
each, greatly simplified transistor 
circuit design.

  The TX-0 served as a prelude to 
the construction of the TX-2, a 
large-scale 36-bit computer.

  The short word length, high 
speed operation and interactive
features of the Whirlwind and 
TX-0 computers greatly influenced 
early minicomputer design efforts 
at Digital.  Some of the engineers 
and programmers who worked 
on these systems joined Digital in 
the early 1960s, and brought with 
them this rich tradition.
