Need Help defining an AS400 with an IP address to the mainframe

APPN and SNA were totally different stuff. SNA has been a communication infrastructure ... that was driven by sscp-ncp (pu5-pu4, vtam-3705). this was somewhat the communication continuation of the FS objectves ... after FS had been end

specific reference regarding major FS objectives:

despite some of the comments in the above reference ... at the time, I drew some comparisons between FS project and a cult film that had been playing non-stop down in central sq. ... at that time I was with the science center in tech sq., a few blocks from central sq.

in the early SNA time-frame ... my wife and Bert Moldow produced an alternative architecture that actually represented networking (being forced to use the label peer-to-peer) ... referred to as AWP 39. a few past posts mentioning AWP39. and NonStop OS ?

my wife went on to serve a stint in POK in charge of loosely-coupled architecture ... where she had numerous battles with the SNA organization. she was also responsible for peer-coupled shared data architecture ... which initially saw major uptake with ims hot-standby ... and later in parallel sysplex.

at the time APPN was attempting to be announced, one of the primary persons behind APPN and I happened report to the same executive. The SNA organization had non-concurred with the announcement of APPN and the issue was being escalated. After six weeks or so, there was finally approval for the announcement of APPN (out of corporate) ... but only after the announcement letter was carefully rewritten to avoid implying any possible connection between APPN and SNA. The original APPN architecture was "AWP164".

also, almost every organization that ever built a box to the "official" (even detailed internal) SNA specifications found that it wouldn't actually work with NCP ... it first had to be tweaked in various ways to make it work.

supposedly the drive for FS ... as mentioned in the previous reference

had been the appearance of the clone controllers.

this is one of the things that I had been involved with as an undergraduate in the 60s. I had tried to make the 2702 telecommunication controller do something that it couldn't quite actually do. this somewhat prompted a project at the univ. to build its own telecommunication controller; reverse engineer the channel interface, build a channel interface card, and program a Interdata-3 minicomputer to emulate 2702 functions. Somebody wrote an article blaiming four of us for starting the clone controller business
