Rubbish the ZX80 and 81 were, they kick started the home computing revolution and the BBC, Acorn, Commodore, Tandy, New Brain, Oric, Atari, Sony, etc came along as a result of Sinclair's efforts.

Not quite, if you look at the timelines.

I was using a NASCOM 1 Z80 machine in 1978, and got my company to purchase an Acorn System One in 1980. (The latter enabled me to demo a concept in 3 weeks when other guesstimate was 6 months:) )

The Sinclair 1000 didn't materialise until 1982. Most people presumed it would have the traditional mark of quality Sinclair had demonstrated since the 60s (with the exception of his calculators).

I had a NASCOM 1 I built from a kit! One of the 100nF ceramic decoupling capacitors was short. I had to find it by measuring the voltage across each using my AVO 8 and looking for the lowest value.

Acorn System series machines were pretty top notch. I found a System 3 in a skip at university and nursed it back to health. Had 6809 FLEX manuals and disks in the skip with it. Had rained all night but fortunately was all saved by a well placed door. Was like a System 1 but eurocard format. Basically a rack mounted Acorn Atom.  I think it is still in my parents' loft. I don't remember selling or trashing it. There are lots of vintage computer bits up there. Probably should sort it.

Edit: there's also a VME SPARCserver and a couple of VAXstation 3100s up there too.

Specmaster:
Wasn't the BBC basically an Acorn Atom?

2 more pages and we will have 500 pages :-+

It was the successor to the Atom, originally called Proton. More memory, different IO and peripherals etc. Plus The Tube which turned it into the original IO host of the first ARM processor which has basically wiggled its way into the fabric of society now.  And that's what happens when you don't start a race to the bottom like Clive did.

The TF930 has an ARM CPU and is made in UK so there's a little bit of an approving nod towards that as a descendent of such things.
