Reading the NMCVR file, I get the impression the Newman device might be a Chaos network interface, perhaps with DMA. No wait, reading NMDFS I see it can talk several PDP-11 machines. So some kind of message passing? The device is also called the "NM-crock", and referred to as a "memory system".

: Yes, that was roughly my guess ([[Talk:Network Control Program (ARPANET)#What is an NCP implementation?|here]]) - "maybe a shared memory between several machines".

Newman
Reading the NMCVR file, I get the impression the Newman device might be a Chaos network interface, perhaps with DMA. No wait, reading NMDFS I see it can talk several PDP-11 machines. So some kind of message passing? The device is also called the "NM-crock", and referred to as a "memory system". Larsbrinkhoff (talk) 08:24, 10 February 2025 (CET)
