In January 1980, Burrell Smith created the first prototype of the Macintosh, which housed a Motorola 6809E microprocessor, 64K of memory, and a 256 by 256 bit-mapped graphic frame buffer. Smith used the Apple II host to synchronize the memory of the two machines through software, rather than designing additional hardware. Steve Capps, an Apple employee, wrote an assembly language routine to transfer data from the Apple II to the Mac prototype’s frame-buffer. Despite some initial obstacles, they were successful in displaying an image on the prototype’s display. However, Jef Raskin, the creator of the Macintosh, was not pleased with Capps’ involvement as he considered him to be a hacker.
