I think the amstrad did so well with being blitzed on every catalog going, so that people who were never going to be able to go out and spend a lump of money in one go could get the kiddies a computer
yes the spectrum cost peanuts then but even so, blowing £100 in one go (how cheap did the spectrum actually end up getting?) was a big deal for some
plus it had classy marketing slogans like "The most legible typeface of any computer in it's class"
which has stuck in my mind due to being such a crap statement
actually, come to think of it, the cpc had some pretty intensive tv marketing didn't it
it's youtube 80's advert searching time maybe.
Hmm, anyone whose mad enough to collect old catalogoues maybe have a look back and see what was going on there too
