Aims are to collect, restore and exhibit all types of early Computers
Electronics and associated peripherals. Their collection includes some LEO circuit boards.
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 at contact@t-Icarvive.org
