Computers in schools at the time were of course pitched at the how-to-drive a word processor level; and all rather a wasted exercise...
I beg to differ - in the 1980s I was with a group teaching with a variety of kit; there were Amstrads and IBM PCs for business applications, BBC micros for programming, Apple Macintoshes for graphic design, and yet more BBCs for CNC machining.
The resource was shared across all schools in the area and catered for all abilities.
A lot of the educational software at the time was cr*p, so a part of our remit was to evaluate what was available, develop our own courses (and software if necessary), and share our experiences.
So, hopefully not a wasted exercise.
