 META II, however, was written in a higher-level metalanguage able to describe its own compilation into the pseudo-machine language.Lee Schmidt at Bolt, Beranek, and Newman wrote a metacompiler in March 1963 that utilized a CRT display on the time-sharing PDP-l.This compiler produced actual machine code rather than interpretive code and was partially bootstrapped from Meta I.

Schorre bootstrapped Meta II from Meta I during the Spring of 1963.
