macintosh 128/512K


Released in january of 1984, the macintosh was the first affordable computer to include a graphical user interface. It was built around the new motorola 68000 chip, which was significantly faster than previous processors, running at 8 MHz. The mac came in a small beige case with a black and white monitor built in. It came with a keyboard and mouse, and had a floppy drive that took 400 KB 3.5" disks--the first personal computer to do so. The mac 512K was a mac 128K with 384 KB more RAM, but was in all other respects identical to the 128K.
