Oh, it's older than that. Later PDP10s (KLs at least) were microcoded. I remember loading the uC update floppies onto the FE's filesystem. The first "VAX" was really a PDP11/60 with exotic microcode, I'm told. (They pulled the same trick later on a VAX 8800 when building the Alpha.) Many of the IBM S/360 models were microcoded.
