In July of 1983 Tandy announced the "Tandy Videotex and Office Information System" that ran under Xenix. It was an early attempt at a hypertext system. It used dialup lines and was hosted on Tandy Model 16b (and later 6000) computers. An 8 port and 16 port multiplexor (that's how they spelled it) were announced. I don't know if either ever shipped. There is some information available in the July 25, 1983 issue of InfoWorld. There is also an article in "TRS-80 Microcomputer News" V5,I 11 (#54 ). I used to run one of these for a local company (that I still work for). Does anyone have the manuals or software from one of these systems? I still have the hardware (not the mux, just the 16b and hard drive). Kelly
