DEC used embedded PDP-11 processors in many different places. There's the console for some of the VAX systems, and I've read some of the DECsystem-10 or DECSYSTEM-20 systems used a PDP-11 as a console system. Other uses of the PDP-11 that I know of are the HSCxx controllers and some of the printers. Where else did the PDP-11 get embedded? I know the HSZxx/HSDxx/HSJxx controllers used an Intel i960 processor, so there's no PDP-11 there. And speaking of the HSCxx controllers, are the PDP-11 controllers customized or is there a standard QBUS or UNIBUS system in there?
