Paul Guilbo wrote much of both and later would write the uCode for the Masscomp FPU and APU. Paul was bitching about the great tool(s) they had had at DEC, so one weekend two of us on the SW team got sick of his bitching a couple of us hacked up a uCode assembler in the same key in Yacc/lex/C (not BLISS ;-).Apparently they were at least advertised as available for the 780.
