This here is one of two Macintosh Plus computers which I own. This one is
the one which I use (whenever I do use it, that is) and the other is kept to be
cannibalized should this one ever malfunction. I've loaded this machine to the
max with 4MB of RAM. It's also got an external floppy drive (with a spare, just
in case), and a ~40MB hard drive mounted in a LaCie external SCSI case. There
is a Mouse Systems optical mouse attached as well, for which there is also a
spare in reserve. All of this equipment, excluding the external hard drive, was
purchased when the computer science department at Brock University sold off the
contents of it's aging (and yellowing) Mac Plus lab.
