Not exactly, but I can get close (I worked for TI ... in fact in the printer division). They were introduced in the early-1970's ... I was using second generation models in 1977. By 1989 (when I joined TI), I'm pretty sure that they had been discontinued, but they were still in widespread use, and were still being supported.
