They did and also used harris, AMD and others as silicon foundries as
the then dec facility was capacity limited. DEC did most of their own
design or formed partnerships with others. The earliest was the 6100
series. Later PDP11 and special support chips.

the chipset or the Pcode? Pcode was easy as any other asm lang. The
chipset had enough stuff available externally o debug easily.
