The Umax "C" series represented the low end of Umax's lineup. Also in the C series were the C500's which also had the same 603e processor as the C600's. The C500's, however, used a less expandable desktop form factor. The C600's had plenty of room for expansion with 4 free internal drive bays. Other offerings from Umax included the higher powered "J" and "S" series. The C600/180 was the low end of the C600 line, which reached its peak at 280MHz less than one year after the C600/180 was released. Aimed at the user with expansion in mind, it is surprising that VRAM was limited to 1MB and, since it was soldered onto the logic board, was not expandable. Those wanting to use a larger monitor and/or higher resolutions would have to spring for an extra graphics card to operate at a reasonable color depth. The C600/180 also lacked on-board Ethernet. On the positive side, the C600/180, like the C500 series, came with an excellent SOHO software bundle which included; Grollier's Encyclopedia, ClarisWorks, 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 most user's needs quite nicely at the time.



While The 1MB VRAM was not upgradeable, the L2 Cache fortunately was, to either 512k or 1MB. Umax also offered the (then) revolutionary "inline" CacheDoubler card which sat sandwiched between the processor and the ZIF slot. Like the G3's backside cache we all know and love, the CacheDoubler card allowed higher speed access to the processor than the standard L2 cache. Motherboard RAM is 16MB and memory is upgradeable to 144MB using the machine's 2 RAM slots

Currently the G3 upgrade paths for this machine is via the L2 Cache slot.
