Makes me walk down memory lane! Here is my list of all the computers that I've owned:

  ZX Spectrum 48k 
   -> Camputers Lynx 48k 
    -> BBC Micro model B 
     -> Acorn Archimedes A420 
      -> Some bog standard PC (initially put SCO Unix on later Slackware Linux 95) 
       -> iBook (clam - came with Mac OS 9 but I upgraded to OS X) 
        -> Custom built PC (with Redhat Linux 9 + Windows dual boot) 
         -> Powerbook G4 
          -> iMac (first 24 inch and now 27 inch).
           -> Macbook Air

Definitely fond memories of the Archie. I think I bought it via Beebug (http://8bs.com/beebugmags.htm) and I had them put in a Midi card (though never got to use it!).

Sorry for the overindulgence :)
