Chiming in to say, this model was my dad's first home computer in the 80s in Scotland. As such me and my brother did not fiddle with it much; however later on we upgraded to the Spectrum ZX 16K with 48K removable daughterboard, a much more amenable model to children. I learned BASIC on that machine and played all kinds of amazing graphic and text games - I wrote about my experiences with this machine on my blog http://nchristiny.com/history/#fnref:fn-2
