SuperMac Upgrade & Troubleshooting
Discussion Forum

The Umax SuperMac C500 represented the low end of Umax's lineup. The "C" series also included the C600 tower computers which offered an additional PCI slot as well as four internal drive bays. Other offerings from Umax included the higher powered "J" and "S" series. The C500/180 was third in a series of five C500's starting with a 140MHz model and ending with the 240MHz. These computers were released in rapid succession and it seemed that as soon as you read a review of one model it was no longer available as Umax had released a successor. Aimed at the home and school users, the C500 was stripped of any "extras" like an internal modem or on-board Ethernet and was priced accordingly. The C500e included an Ethernet card and the C500i a modem. Either option added to the cost of the plain C500 of course. The C500 came with an excellent SOHO software bundle which included; Grollier's Encyclopedia, Claris Works, Quicken, Now Utilities, Conflict Catcher and Adobe's Page Mill to name a few. The internal 8x internal CD-ROM while no







speed demon by today's standards, was sufficient to meet the targeted user's needs quite nicely. Less forgivable is the 1MB of logic board VRAM which cannot be upgraded making use of larger monitors problematic. On the positive side, the L2 Cache was upgradeable to either 512k or 1MB with offerings available from several vendors. Umax also offered processor upgrades that fit into the (then) revolutionary processor ZIF slot.
