Macintosh 512k

Photo of the front of the Mac 512k: the opening is the floppy; at the bottom is the keyboard connector that used a phone like cable (category 3)

Mac512k back image

Photo of the back of the Mac 512k: ports are at the bottom (mouse, floppy, printer, modem, sound) with the black hole on the right being the power plug. At the bottom on the side (look at the right corner) are two buttons that were the interupt (programmers) key and a reset button.

The complete Mac512k set. I believe the keyboard is larger than what the original would have been (since it has a numeric keyboard). The Mouse is original. The keyboard uses a CAT3 (phone) type cord and the mouse uses a nine pin serial (rectangle) connector that plugs in on the back. The Apply mouse pad is a from the mid 1990s. There are also a couple of manuals sitting next to it.

MacPaint with the words "Hello World!" on it.

Another picture of the back.
