When the first Macintosh model (actually titled the “Macintosh 128K”) hit the market in 1984, it featured a 3.5-inch floppy disk drive built by Sony, the industry standard at the time. Originally, Apple had planned to include its own proprietary Twiggy 5.25-inch drive, but engineers deemed it unreliable, despite its larger storage capabilities (860 KB to Sony’s 400KB floppys).
Now, one of the original prototypes has surfaced on Ebay, featuring the mythical Twiggy drive. The auction is starting at nearly $100,000, but if you got money to burn, it could be a good investment. This thing belongs in a museum.
