I think you meant either "stored in RAM" or "not stored in ROM". The LSI-11 front end for the VAX-11/780 (and other early VAXen?) was connected to the SBI (Synchronous Backplane Interconnect--the system bus) and performed three main functions: microcode load and system bootstrap initiation, interface for the system console (originally a LA-36 dot matrix terminal), and some system diagnostics. CPU microcode was stored on a 5" floppy disk connected to the LSI-11 and was loaded into RAM at system power-up. -Paul W.
