While working on APL\360 I spoke to Adin Falkoff about the formal description of System/360. Before the announcement of the 360 there was an audit committee within IBM. It's mission was to ensure that the five initial 360 models conformed to the standard architecture. Some minor deviations in areas such as machine checks etc were approved by the committee. The Falkoff, Iverson & Sussenguth model was subject to review by the audit committee.
F, I & S was to my knowledge the first public use of [[shared variable]]s. There was also an unpublished description of the 360 I/O channel. IMHO the channelmodel was flawed because it used a single shared variable for inbound and outbound tags. This made rperesentation of certain error conditions impossible. It would have also made description of the 370 Data in and Data out tags impossible. Roger D. Moore [[User:Rdmoore6|Rdmoore6]] 21:45, 28 December 2005 (UTC)
