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.
