The original Macintosh, the reason 1984 was not like 1984... according to the Superbowl commercial anyhow. I was walking around Value Village in grade 11 when I stumbled upon this lovely computer, complete with carrying case, keyboard and mouse.
Over the years I have found an original ImageWriter printer and an external 3rd party 400k Floppy drive. Although the original, this computer is quite limited having only 128k of RAM for a full graphical system. I'm running system 0.98 off a single floppy disk.
The floppy disk makes quite a distinctive whirring that is quite satisfying when booting and loading. For booting from a floppy system 0.98 is quick to boot.
