Like many of you out there, I had been salivating over Mac OS X since it arrived last year. There was one small issue: I was using a Umax SuperMac S900, and 604e support was less than forthcoming from Apple, so unless there was a new Apple G3 or G4 machine in my future, I was […]

The SuperMac C500 and C600 used the PowerPC 603e CPU in a great variety of speeds, ranging from 140 MHz to 280 MHz on a 40 MHz system bus. The best performance, short of a G3 upgrade, comes from using a fast CPU along with the Cache Doubler module.
The Umax SuperMac C500 and C600 were the first “Power Macs” to have their CPU in a ZIF socket, making upgrades very easy. Having a C500/200 at work and finding an incredible garage sale special on upgrades from Small Dog Electronics, I decided to test the 240 MHz upgrade and the CacheDoubler.
There are plenty of sites offering installation and troubleshooting advice for Mac OS 8.5 – at least for the Power Mac user. Since neither Apple Computer nor Umax Corporation provides any support for Mac OS 8.5 on SuperMacs, this page exists to cover problems specifically noted by users of the Umax SuperMac series of Macintosh […]
The Umax SuperMac J700 was the first Power Mac clone that I benchmarked. My J700 shipped with a 180 MHz 604e CPU, and has 104 MB of memory and a Quantum Fireball 2110 hard drive installed. It shipped standard with an ixMicro Twin Turbo 128 video card, which I replaced with an ixMicro Ultimate Rez 3D […]

It may have been the least expensive Mac OS computer of its […]
