Umax SuperMac J710

The SuperMac J710 was the last new model from Umax, and only about 50 were ever produced.

Umax SuperMac J710Combining the form factor of the compact C500 with the power of a PowerPC 604e or G3, the J710 would have been great for power users on a budget. About 90% shipped with a 200 MHz 604e, a few shipped at 225 MHz, and the G3 model was intended for internal use only.

The 604e models would have been upgradable to a G3 using Umax’s own daughter card.

The J710 looks just like the C500 and uses the same ZIP (or PEZ) socket for processor upgrades.

Although Apple certified the model for sale, its refusal to renew Umax’s license to produce Mac clones lead Umax to abandon the J710.
