COMPUKIT 1  Logic Simulator Digital Computers (x2)  c1970

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.

COMPUKIT 1  Logic Simulator Digital Computer  c1970

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.

These are I.C. based types of Limrose Logic Simulator Digital Computers here.  c1970's

These types of Limrose Logic Simulator Digital Computers are twice the dimensions of the COMPUKIT 1 (The size of four COMPUKIT's.) and with their own built-in PSU supplies.

The Combinational type of Limrose Logic Simulator. (There are 4 of this type here.)

The Sequential type of Limrose Logic Simulator. (There are 3 of this type here.)

The COMPUKIT 1 Logic Simulator Digital Computer from Practical Electronics 1970.

The early release of COMPUKIT 1 had a white background identification area.

This appears to have changed about October 1970 to the white text and graphics area.

Also noted is that both the COMPUKIT 1 Deluxe and COMPUKIT 2 are available in Dec.
