Honeywell 316

Are we even sure it was a Honeywell 316, since the first reference says it was a Honeywell 516 ContivityGoddess 23:05, 21 February 2007 (UTC)[reply]

The Honeywell 516 was the milspec version of the 316 (I believe that was the only difference). It was a result of Frank Heart's attitude to engineering - he insisted they use the ruggedized one. First TIPs and later IMPs used the 316. toresbe 16:40, 22 February 2007 (UTC)[reply]

the first ones were DDP516 and there were pictures at BBN of a special edition DDP516 with massive cad plated shipping loops for winching on board ships. By the summer of 1971 the DDP316 was the machine of choice. There was also a flirtation with the Lockheed SUE. William01p (talk) 13:38, 11 August 2009 (UTC)[reply]

The first routers

These units were the first generation of what is called a router today. I dont know if a common reader could gleen this from the information as presented. Since I feel this way, I added three cites to confirm this and also contact Steve Crocker to confirm. In an email also stated they just made up the term "Interface Message Processor" to define the thing. --akc9000 ^{(talk • contribs • count)} 12:53, 22 June 2007 (UTC)[reply]

My recollection of talking with the UCLA guys who maintained the IMP was that they were the interface between a computer and the ARPANET. Each one was custom designed to interface with the particular computer it was attached to. These were mostly mainframes. Issues would occur when there were hardware failures as there wasn't anyone to turn to to fix them. I tend to look at them more like a NIC (Network Interface Controller),Saltysailor (talk) 07:04, 20 May 2008 (UTC)[reply]

The UCLA IMP interfaced between the SDS (later XDS) Sigma 7 and the external phone lines. The IMPS were not custom designed -- only the interface board, provided by the host site, was custom designed. The one in the UCLA IMP was designed and built by Mike Wingfield, and worked the first time. My supervisor, Charley Kline, is the person who made the first remote login. A good resource is "Where Wizards Stay Up Late" by Katie Hafner -- 184.189.217.91 (talk) 01:27, 19 December 2015 (UTC)[reply]

first message?

Here it says it's three letters, "log". On the ARPANET page proper, two letters - "lo" (then a crash). Which is true? —Preceding unsigned comment added by 193.63.174.10 (talk) 09:50, 6 July 2009 (UTC)[reply]

Both, of course ... the crash happened when the 'g' was entered. After the bug was fixed, "log" was successfully entered. The bug was due to a buffer overflow ... entering the 'g' caused "gin" to be echoed as an autocomplete, but the software couldn't handle more than one character at a time. -- 184.189.217.91 (talk) 01:31, 19 December 2015 (UTC)[reply]
