I have had long experience of computing, starting with a teletype terminal connected to a dial-up time sharing system at my secondary school (writing 40 line BASIC programs for ‘O’ level Computer Science!) and moving on to a Sinclair ZX81 with 1K of RAM…

Some of that computing history I am gathering here, initially a project to create an archive of the products of the Chase Group of Companies.

Other areas of vintage computing may be added as I come across them.
