The son has expressed an interest in programming and, as far as I know, is not doing anything in school that relates to this. His father is keen to bring this on.
My start in programming was with home made boards with SC/MP, 8080 and Z80 chips, so I'm completely out of date and past it.
The obvious thing is a Raspberry Pi, but is there anything better out there now? I've never used any of these things. There seems to be plenty, maybe too much, variety in how and what these little boards can do. I have no idea whether he has access to a TV or monitor at home with his mum. I have been told by my son who works in a power-programming environment that there are now some Intel-based boards that "everyone is buying for projects".
I suppose the only answer is for me to buy something and see for myself. I doubt, though whether I have time to do anything justice or do anything beyond adding to the noise. I could donate an old laptop running some version of Linux and donate some old books on C, but I doubt if this would be much use in the family circumstances.
Any views gratefully received.
