Lol! Good topic!!
My first computer in the late 70's was an Acorn System 1 (see http://en.wikipedia.org/wiki/Acorn_System_1
This was quite swiftly followed at HUGE expense (£360 in about 1979, which is about £2420 at current earnings apparently) by a Nascom 2, in turn followed by a MAP-80 system. I remember programming in Crystal BASIC, an extensible BASIC interpreter. A friend had one too and between us we wrote a disk operating system for them.
We still laugh about buying 16K (yes, K - not a misprint) of RAM for £64!
Then I moved to a 80386 system and Turbo PASCAL, then Minix, then Linux...and the rest is history!
Somewhere in there I bought a BBC Electron for the kids, on which I absolutely got hooked on Elite. Now I enjoy playing Oolite occasionally and X-Plane 10 more often, on my multi-core home-build with masses of RAM and a powerful video card.
But most of all, like all the rest of us, I am really excited about getting my hands on a Raspberry Pi and recapturing some of the smell and feel of a single board computer.
