Sinclair QL+ Prototype recreation (scale 1/1)

This is my tribute to Rick Dickinson's work, the Sinclair QL+ as pictured in the superb 'Delete' book by Paul Atkinson.
This prototype never reached production status, but still after more than 30 years, the design remains impressive and eye catching. I tried modestly to follow the original design as much as possible, only changing the internal of the machine by a raspberry pi 4. I hope you will enjoy this tribute and the feeling it provide as much as i did by researching and re-creating this device, even if it cost me hundreds of hours... ;-)
