This is the machine that I learnt to program in assembler on. I eventually built a video display from a design published in Personal Computer World back in the days when they actually had circuit diagrams and hardware construction projects. Ordered all the TTL and memory chips from the US because at that time it was about twice as much to buy them in the UK even with shipping. Does anybody have any information about the SC/MP ? I know it was a bit- serial processor but I can't remember much about the architecture. There were several computers in that era based on it. I'd love to hear other recollections of the UK home computer scene from around that time. Simon
