I was thinking about it and what we used to pay back then, and I had to look that Tandy up, because that price, I just never remember them being that expensive. It turns out the part where it says it had the IBM Microchannel 32 bit architecture is why the price was so nuts. ISA was 8 or 16 bit depending on the card which was what most cards at the time used. Microchannel cards obviously doubled that. This really was for professional applications.
Meanwhile for us mere mortals $2500-3000 could have gotten you a decent 386 PC around that time. Still excessive don't get me wrong especially if you take inflation into account and today's prices. But in that respect whats funny is we are flabbergasted by $8500, but take inflation into account, its over $16,000. Heck $3000 in 2017 dollars is almost $6000!
