Apple II wasn't very common in the UK, not even the Europlus model was that common. Most classrooms at that time would have used a BBC Micro or BBC Master since those where the contract machines for schools and sold at discount. I remember a lot of schools had PCs from RM (Research Machines) then ultimately everything and i mean everything went DELL, i don't remember any other companies desktops in any building anywhere. Schools, doctors, universities, libraries, police, random stores ect. I remember there was a very early Power Mac on a trolley in primary school and that was pretty much the school computer till they got DELLs in.
I got these pretty cheap a few years ago; first that's a Mac Classic II which has a 68030 cpu but only a 16bit bus so its around 40% slower than a Mac SE/30 which has a full 32bit bus. However it doesn't matter much because of the type of software the Mac Classics run, if you wanted speed you bought a desktop Mac with a colour monitor and those had like 040 processors and stuff that where faster.
That's an Apple IIE enhanced in the bottom 2 pictures, i got lucky when i bought it. I saw it with box and manuals and i ended up winning an auction on ebay for way less than it was worth. Came with a 80col card with ram, a z80 co processor card for running CP/M and one disk drive among some other cards.
They where interesting for the time but bloody expensive. I always saw them as high end machines for desktop publishing and design. Something you bought to use certain software.
