Jörg Charles River UNOS was actually Tandy's first non-TRSDOS choice for the Model 16; Microsoft won the platform to Xenix by threatening to withhold BASIC and Multiplan for all other Tandy platforms if Tandy went UNOS [1]. Xenix on the 16 in 1987 was my first Un*x system (starring out a letter in Unix was to keep from trademark violations......) and 3B1 Convergent-written AT&T-labeled SVR2 was the second, with the oddball Apollo Domain/OS (change an environment variable and change the system from 4.2BSD to SVR3!) the third. A QIC-120 packaging of SLS by Mac's Place BBS was my fourth [2], and I've used Linux in some form ever since. How is this related to CentOS? Peripherally only, in that there was once a Project-16 newsletter post to comp.sys.tandy about the 16B made by one John M. Hughes (bang-path e-mail address of noao!coyote!moondog!proj16) back in January of 1991 [3].......I would love to come across a collection of these, as my main box at that time (running C-News) was a T6K with a pair of Rodime 70MB drives and a Maxtor XT-1140 140MB drive for the news spool.
