Ah yes, we remember them fondly (!)
I built my first computer from kit , an "Acorn Atom"!
A surprisingly good machine for it's time. A real keyboard, decent interfaces and the potential to expand as your budget/knowledge allowed. I doubt there are many "young bucks" out there now that even know what Machine code is!
I wish now that I'd kept it as a momento of a time when I did "real" electronics....
