Very interesting, thanks for the pointer.

It contains one thing that I'm curious about: "the Interface Message Processor
(IMP). This were initially attached locally to Host computers by a parallel
interface." (bottom of pg. 2) I'm unaware of this stage; I thought they always
used the 1822 bit-serial interface? I'd look at my copy of the BBN proposal
(in response to the DARPA RFP), which probably talks about whether the plans
were always for that interface, but alas my son and his wife are asleep in the
room it's stored in, so I can't. I suppose it's possible a first IMP or so
were prototypes, and initially used a parallel interface, later replaced by
the 1822 interface, but I don't recall hearing about that. Can anyone expand?
