SMI); as were a number of other forms such as Imagen.

Little known details... Masscomp (as ex-DEC HW folks) used the Valid
systems also.  tjt and I hacked together a microcode assembler in lex/yacc
over the course of a few days/weeks that was the same syntax and features
of the old DEC internal microcode assembler Paul Gaulbau and teams had used
on the Vax et al. (I might even have it somewhere - Clem-isms - spelling
errors/dyslexia in the comment headers)  DEC-West had a number of
macro/library files they had developed for the Valid.   One night mag tapes
of each mysteriuslly appeared at the other firm. ;-)
