This could be the rarest Mac compatible ever made. Outside of a few prototypes, only about 100 McMobiles were ever made.
The first prototype (pictured here) used Mac Plus parts in a Plexiglas case to produce a 15 pound laptop with 15-30 minutes of battery power – that’s a bit lighter than the Mac Portable and about half the weight of the Mac Plus that the parts came from. The second prototype was a bit smaller, and the third was smaller yet.
Yukio Tezuka, the designer of the McMobile, eventually raised enough money from investors to contract for 100 McMobile cases. Unfortunately, by the time the case manufacturer delivered, Apple had already unveiled the Macintosh Portable. Despite this setback, Tezuka managed to sell his entire inventory.
