I have one of these units, I think. Mine is called the "745 Portable," TI Part No. 0983801-0003 and is about the size of an old Remington portable typewriter. Looks like an early 1970s model with a standard phone coupler and a 15-pin connector with an 8/7 pinout. Mine is in taupe colored plastic with a cover and four plastic connectors similar to the ones used with Osborne and Kaypro keyboards. The quality of construction is quite high and the keyboard has a nice feel. There is a picture of one shown at VCF 1.0 at: http://www.rdrop.com/~jimw/vcf-09.jpg Is it the same unit, Don?
