An interesting experiment! Unfortunately since I moved continents I don’t have any of that old gear any more… but the concept is great and I apply it for more things.

My first computer was a Sinclair ZX80, quickly followed by the awesome Acorn BBC/B (Acorn completely missing from oldcomputers.net!)
I learnt programming slightly before, on a DEC PDP-8 (in VT78 with two 8″ floppy drives and a line printer) at a local club.
