This very early prototype ca. 1981 of the Apple Macintosh was hand built by Brian Howard and Dan Kottke. The prototype uses an external Apple II power supply and Apple Disk II floppy drive. It has a single bootstrap EPROM, which loads a 68000 version of the Lisa Monitor, written by Rich Page. Apple released the Macintosh computer in 1984, introducing the general public to a user-friendly personal computer.
