UPDATE: Personally-owned by Apple executive Del Yocam.
Rare Apple IIGS computer personally-owned by Apple executive Del Yocam, who was the executive vice president and general manager of the Apple II group (1983-1985), Apple's first chief operating officer (COO) (1986-1988), and president of Apple Pacific (1989). This unusual example has a "Del Yocam, Special Edition" emblem on the right side of the faceplate, and lacks the standard Apple Computer, Inc. manufacturer's label on the bottom of the case. Complete with the original shipping box, identifying the model number as "A2S6010" and bearing an affixed Apple Computer, Inc. shipping label addressed to Del Yocam in Scotts Valley, California. The computer is in very good to fine cosmetic condition, with some yellowing toward the rear of the case; the computer boots and appears to be fully functional, but needs a startup disk.
This rare computer appears to be a one-off, created especially for Del Yocam himself. While Apple did release a special 'Woz' limited edition of the Apple IIGS to commemorate the 10th anniversary of the Apple II series, there is no record of a 'Del Yocam' edition ever being offered to the public.
