APPLE MACINTOSH CENTRIS COMPUTER + KEYBOARD + MOUSE.

It doesn't have a cd rom but does have a floppy disc. I don't have a monitor or a cable adapter for a VGA monitor but I have used it in the 90,s with a home made cable and I have a circuit diagram for how to make one. The CMOS battery may need charging or replacing.

It has a 650MB hard drive with an old version of the Mac OS.

This is a older than vintage Apple computer which may be rare as the model went through a few changes year by year over about three years.

This model is the Macintosh Centris 650.
