Hi,
I can remember black and white TV and the joke later about using a photocopy for a television license because there were so many repeats (of black and white shows)
In '90 I started nursing course and the introduction to computer was a Mac lab running System 6 computers and do matrix printers.
In '91 I got my first Mac, a Performa 400 as they were called it here running System 7 (still runs)
Then a Blondi Blue iMac that sadly died.
Then a G4 Mirrored Doors tower that I stuck extra drives in (gets booted every day)
I did have everything from OS 9.2.2 to Leopard (the last it can run) on those Drives and various Partitions on them.
Again two of those have let go.
A MacBook Pro version 1,1 followed (Only runs three versions of the OS and has been superseded by Core Duo2 Intel chips.
Current machine is the iMac listed.
We bought my son a Tangerine iBook that was my Father-in-laws first computer that has made it's way back to us.
It has OS 9.2.2. and OS X 10.3 squeezed on there.
Both my son and daughter drifter to Windows as the School that they went to was not that Mac friendly but both have come back to Macs.
I must admit to keeping mostly to Messages now that iChat has been iOSed
