I worked at one of their computer centers - I wasn't a great salesman either, because I didn't want to sell something to someone who didn't want it, but I did all right. They had a heyday and blew it.
I gotta admit, though: the TRS-80 series was a wonder, all told. You could legit go from a Model I to a 6000 running a full UNIX (Okay, it was XENIX, but still!)
You'd never WANT to do that - even running the 6000 on XENIX was a bad idea compared to running XENIX on an 80386, never mind that it was XENIX. This was back before SCO turned evil, anyway. But you COULD!
It would be a dream job for a young ham but a disaster for a corporate guy putting together training for non-ham employees that would be making minimum wage.
