There were many countries that the Classic Mac never managed to penetrate in any meaningful way. Apple didn't get a look-in on their traditionally lucrative educational market within the UK.
Apples dominance of the educational market in the US was impressive. Before the Mac came out, I was taking classes in Fortran and Basic programming in computer labs filled with Apple IIs. I later had a job in mass mailing--also known as junk mail--and one of our clients was Apple and at the start of every school year we would send postcards advertising the latest Macs to just about every School and univeristy in the US. The postage bill was around $50,000 and this was at early 90s postage rates using heavily discounted mass mailing postal rate formulas.
