Apple Powermac 7100/66mHz Computer

The 7100 was the middle of the new PowerMac range, boasting better performance and features than the 6100 but still a little way behind the top-of-the-line 8100. Housed in a slightly re-styled Mac IIvi case (the same hideous case seen on the Mac IIvi, IIvx, and Quadra 650) the 7100 ran at a blistering 66MHz (later speed bumped to 80Mhz) a whole 6MHz faster than the 6100, came equipped with 8Mb of RAM as standard (expandable to 136Mb)(Note: The 7100 has four RAM slots which, in theory allows 4x64Mb of main memory but, in reality, will only accept 32Mb modules), an optional CD-ROM drive, and four expansion slots (in stark contrast to the 6100′s single NuBus PDS slot). Like the 6100 though, the machine was also available in an ‘AV’ flavour whereby it came fitted with an AV card (plugged directly into the PDS slot). Not only did this do away with the need to use the onboard video card (which leached memory from the main RAM) but also upped performance considerably.

The Apple Power Macintosh 7100/66, based on the Carl Sagan (BHA, LAW) architecture, features a 66 MHz PowerPC 601 processor, 8 MB or 16 MB of RAM, and a 250 MB or 500 MB hard drive in a high-profile desktop case.
