The Umax SuperMac J710/200 stands out as a rare case of a Macintosh clone that never shipped. Based on the Alchemy architecture, this compact desktop system was unveiled at MacWorld Expo 1998 but was pulled before hitting production. It was the only member of the J700 series to use the slim C500 case, making it unique even within Umax’s lineup.
Equipped with a 200 MHz PowerPC 604e processor, 32 MB of RAM, a 3.0 GB IDE hard drive, and a 4 MB Matrox Mystique video card, the J710/200 targeted mainstream users wanting a low-profile Macintosh-compatible system. However, it remained vaporware—announced but never shipped.

A Ghost from the Clone Era
Although the Umax SuperMac J710/200 was never sold, it reflects the final moments of the Apple clone licensing era. Its limited expansion, slim form factor, and announced-but-not-shipped status make it a curiosity among collectors and historians. The model is also notable for being one of the few Alchemy-based Mac clones with a compact desktop footprint.
The J710/200 lives on in marketing materials but was never added to Umax’s price lists and remains one of the rarest references in the Mac clone timeline.
