Re: Amstrad PC
The difference between the screenshots on the back of the F-19 box compared to the 4 colour mono CGA was pretty astonishing! (Of course the 1512 wasn't actually limited to standard CGA but effectively nothing supported the proprietary 16 colour mode.)
Returning to the PCW, I learned touch typing on one as the Office and Information Studies classrooms were kitted out with these (computing was BBCs and eventually Mac SEs! (edit - having Googled I see they were actually Macintosh Pluses with external hard drives)
They were very productive machines - no distractions from Fakeface alerts, email or YouTube, just a very decent Word Processor. I also liked the 3" discs, they seemed very solid compared to the 3.5 and 5.25" competition.
