A seller going by the ID "zieglerc" on Ebay has put up for auction a prototype model of the Macintosh Portable, the first Mac "luggable" computer from late 1989. The prototype comes complete a case, FCC non-compliance warnings and a "property pass" allowing it to be checked out from the company's headquarters. The unit is described as being in nearly mint condition with the exception of a non-functioning (but included) original battery.
