My first computer was an Acorn Atom. State of the art with a 6502 processor and 12K RAM! And you could program it in assembler also!
I still have it, even though collectors are offering ridiculous sums of money for it.
Is is nice to have been there from the beginning, yes, it gives a nice insight into how things actually work and developed.
The Atom was the 'parent' of the Beeb. I think it was even available as a kit. I'm not sure if I ever used one. You should hang onto it as a future antique.
I do remember soldering it together, yes 8-). I don't think I will ever sell it.
