Early Sinclair business model?
When - in the 70's I wanted to learn about these new-fangled 'microprocessors', a director-friend of mine at Courtaulds in Coventry (defunct) told me they were developing around a 4-bit processor, the Intel 4040.
He repaid my enthusiasm by giving me the Intel 4040 user manual. I still have it, somewhere.
Unfortunately for me it was the equivalent of being given a pillow-full of feathers, a bottle of glue, a stepladder, a book by a bloke called "Icarus" and told "Now you can learn to fly". I didn't have a clue what the state diagrams, etc. meant.
Couple of years later, I got a Sinclair MK14. Eventually. By 'eventually', I mean that I paid for it, and after several (mostly unanswered) phone calls, it arrived, after about 6 weeks. Cost me a lot of money - can't remember how many shillings, but a lot for me at the time.
Point is, www.commodoreusa.com can't give prices. Neither can www.cybernetman.com/ - they'll send a quote - or call me - I suspect they seem to be just trying to judge the level of interest before they make any. As, I suspect Sinclair did (It was quite successful - 50,000 sold - and to me, it was a godsend)
