The Compukit 1 was created by Dr Ravi Raizada, who founded Limrose Electronics of Lymm, Cheshire, it was designed as a logic trainer to teach people how basic logic gates operated.

This is the second Compukit 1 here, together with instruction manual 'Introduction to logic and digital computers'. This being a 38-page black and white printed instruction manual.
The kit belonged to the late Owen Bishop (1927-2016), Owen was an electronics book author, he also wrote regularly for electronics magazines, e.g., Practical Electronics from the early 1970s.
In 1980 he started writing some of the first home-computing and programming books for the BBC Micro, Amstrad, Commodore 64 etc. He also wrote many electronics coursework books.
Owen's daughter Dee, adds a memory of her father.
I remember lots of circuit boards and electronics items, he used to work in the 'boiler room' at home, which was set up as a sort of workshop/lab and where he used to spend many hours working.
The Compukit 1 is another good example of our excellent British ingenuity in bringing computing to the people back in 1970.
