> I think their cash registers ran SCO Xenix.

Tandy had a Xenix license from Microsoft and shipped a version on their TRS-80 Model 16 and Tandy 6000 machines (both of which were Motorola 68000-based). It would be interesting to know how much of their own stuff they used internally. I have a recollection of a (potentially apocryphal) story the TRS-80 Model 1 had a "fallback" use as an in-store management computer if they failed to sell.

Free OpenServer appeared in 1996. The cash registers were running on the x86 platform, for sure (68000 was a dead architecture for general purpose computing by then - Apple had been on POWER for several years).

I'm talking more like the late 80s when I was giving my address info to clerks at Rat Shack who were typing it into some kind of green-screen app on what, if memory serves, kinda looked like a Wyse terminal.

That could very well have been a Model 16 running Xenix 68k.

From memory, the two serial ports could run classic getty processes.

		Yep-- that's what I was getting at. I'd love it if somebody w/ real Tandy corporate experience appeared in this thread and discussed it... >smile< Here's hoping for the power of Hacker News.
