Re: Dim Memory
The IMPs communicated with each other but the interface between the IMPs and a local computer was a bit serial interface with a specification. Each client had to build their own interface to the IMP. This was the day when machines had all kinds of bit lengths (12, 15, 18, 20, 24, 36 etc.) and the ARPANET protocol was designed to line up words if the communicating machines were of the same word length and all of the bits were preserved if they were not.
