Then there is the DS100, which is the first LAT terminal server. MMJ jacks, if
I remember right.
I don't know if it's only in the prototypes or also in the production units,
but... I remember that if you look inside, you may see a PC board much smaller
than the box, with wire assemblies leading from the PCB to the terminal
connectors. The reason is that Ken Olsen intervened in the design when the
device was about ready to ship -- he changed both the box size (making it 19
inch rack mount rather than SB-11 size) and the connectors (from some 8 pin
connector I don't remember to his newly invented MMJ connectors). This is how
KO acquired the nickname "Chief Connector Architect" in some DEC circles.
