As I make panels I have the dimentions for PDP-8/e (two types) ,8/f,8/m and 8/I.
All except the 8/I start from the same 3mm Perspex blank. The holes are laser cut.
Cutting square or rectangular holes in thin plastic sheet is not for the faint hearted.
The round holes need lining up with the switches behind them.
By all means have a go using proto boards Pi etc
I you deviate from the DEC bus and wiring structure then all the vast documentation
So see how you get on. I'll always have ready made available.
