Macintosh Plus (Still have, still works)
Mac Classic (Sold)
Mac Classic (We had two)
Mac Performa 250 (Still have, still works like a trooper)
Mac LC (Still have, needs a working monitor)
PowerBook 100 (Sold)
PowerBook 140 (Still have, don't use much)
PowerMacintosh 5500 (briefly)
[Large gap in time here, I know but my dad was using the PowerBook 190 until last year, when his school bought him a clamshell iBook]
Clamshell iBook (Dad's current laptop)
iMac G3 350 (Dad's current computer)
iMac G3 350 (My current server/Mum's computer)
PowerBook G3 Wallstreet (broken screen now, since my brother stepped on it
)
PowerBook G4 Aluminium (My current machine)
The thing I always found most impressive was how much use my dad was able to squeeze out of a PowerBook 140. It's so amazingly old nowadays, yet he was using it as his primary machine, quite happily, until he got the Clamshell and iMac. Sometimes it's just fun to plug the machines in and see the old things whirring away.
The Performa 250 was my brother's when I had the LC (both were colour, both had HDDs. The Performa had a smaller screen, and could render far more colours, but otherwise, quite similar). I remember at the age of 7 networking the two. That's just incredible to me.
