The Power Computing PowerBase models of Macintosh compatible clones hit the market in the late summer of 1996. Offering an excellent price/performance value these consumer orientated machines proved very popular and were hailed by most Mac orientated magazines as better value than Apple's own offerings which cost more and were less powerful. It was in large part due to the commercial success of Power Computing, the marketing hype that surrounded the company and the fact that Power Computing was going for Apple's jugular, that Apple pulled the plug on cloning - a controversial decision at the time.

The PowerBase 180 was the low end model of a three unit family that also hailed 200Mhz and 240Mhz models. It sported a 180Mhz 603e processor and a 256K L2 cache. The 603e processor was the low end PowerPC chip of the time and was also very low in power consumption.

The PowerBase's processor exits on a removable card and is thus replaceable with a faster processor. The 180 also shipped with 16MB of EDO (Extended Data Out) RAM. RAM was expandable to 160MB using 3 DIMM slots. The machine had 2MB of Graphics memory (expandable to 4MB for more colors at higher resolutions) and had a special chip for handling 3-D graphics acceleration. There are 3 full size PCI slots. The machine has a 8x CD ROM and a pokey 1.2GB IDE drive. One innovation the was the inclusion of a PS/2 keyboard port. You had a choice of cases for the PowerBase machines; a desktop model that had no free drive bays and a minitower that had two free, front accessible 5.25" drive bays.
