> I did the same, but with Tandy 4000s.

Never saw one of those. Tandy computers did exist in the UK, and even here on the Isle of Man there was a single Tandy's store. (They weren't called "Radio Shack" here.) But while they sold lots of spares and components and toys, they didn't sell that many computers.

Well, yes. Flipside of the same coin.

Expensive RISC computers were doomed. Arm computers weren't expensive back then: they were considerably cheaper than PCs of the same spec. So for a while, they thrived, then when they couldn't compete on performance they moved into markets where they could compete on power consumption... which they then ruled for 30 years.
