Well, my first LSI-11 was a Terak 8510. It had 28KW of memory and
4 8" RX01 compatible floppies and an LSI-11/02 CPU. And I developed
programs in Pascal, Fortran-77 and COBOL (yes, COBOL!!) on it. Now,
there is slow. I would gladly take a screamer like any Pro over doing
software development on the Terak.
