A prototype of Apple’s first portable Macintosh is now available on eBay.
“This an absolutely mint, flawless, clean prototype Macintosh Portable that wasn’t intended for sale — the label on the bottom notes that “it’s intended for demonstration purposes only and doesn’t include the necessary certifications.” The unit also includes the original soft-shell case, a system update floppy, original power adapter, and a signed form showing that the unit was checked out of Apple Computer in August of 1990.
Note that this machine doesn’t currently turn on. It appears the issue is that the lead acid battery (which is original and currently installed) no longer holds a charge, and Macintosh Portables cannot boot without a usable battery.”
Interesting to note is the prototype unit featured a trackball on the left, while the publicly released 1989 version (pictured below) had its trackball input on the right side:
The starting bid is US $1,750.00.
