Time-Line computer Archive Ltd is a not for profit company, our aim is to collect, restore and exhibit all types of early computers and electronics.

We hope that our website will give an insight to the development of computing and will help give inspiration to other people to collect rather than throw out historical electronics.

We also would like to make a record of peoples experiences of early Computing and Electronics primarily from Scotland and the North of England but also from Great Britain generally. If you have any Experiences of early computing or Electronics please don't hesitate to contact us.

Digi-Comp 1

 

The Digi-comp 1 computer comes as a kit, mainly plastic with some metal components, it dates from 1963.

 

 There are no electronic components it is a totally mechanical computer, When I started to assemble the system I thought

it would never work, its too mechanical!.. but it does.


It is also possible to program the computer by changing the little pieces that push onto the plastic flip-flops “ Logic Tubes”.

I found great care had to be taken when changing these tubes, they are a very tight fit and with the flip-flop being

plastic, disaster was only a slip away.


The readout can be seen on the left hand side of the computer, there are three windows, each window you can read

either 1 or 0. Next to the readout Window, you can see a front panel card is inserted.

The front panel card on the Digi-Comp at the time of the photo was for Experiment 5 in the book “Sequential Bank Lock”.

The computer is activated from the right hand side by pushing and pulling on the white plastic slider, it has the

words "Clock" written on it.

 

 I think its real triumph of Engineering and Great fun was had by all!
