The Power Macintosh 6100 (also sold as the Performa 6110 – 6118 and the Workgroup Server 6150) is a personal computer designed, manufactured and sold by Apple Computer from March 1994 to March 1996. It is the first computer from Apple to use the new PowerPC processor created by IBM and Motorola. The low-profile ("pizza-box") case was inherited from the Centris/Quadra 610 and 660AV models, and replaced the Macintosh Quadra series that used the Motorola 68040 processor, Apple's previous high-end workstation line. For the consumer market, the 6100 was re-branded as a Macintosh Performa with model numbers in the 6110 – 6118 range denoting bundled software and hard drive sizes. An Apple Multiple Scan 15 Display and AppleDesign Keyboard were included as part of the package. For the server market, a variant was offered with additional server software, called the Apple Workgroup Server 6150. The 6100 was discontinued without a direct replacement. Overview The 6100 was introduced alongside the Power Macintosh 7100 and Power Macintosh 8100 and occupied the entry-level role of the new Power Macintosh family. MacWorlds review of the 6100/60 noted that "Not only has Apple finally regained the performance lead it lost about eight years ago when PCs appeared using Intel's 80386 CPU, but it has pushed far ahead." Performance of 680x0 software is slower due to the need for System 7.5's new Mac 68k emulation layer, but MacWorlds benchmarks showed noticeably faster CPU, disk, video and floating point performance than the Quadra 610 it replaced. The 60 MHz models were upgraded to 66 MHz in January 1995. Apple also released a PC-compatible model of the 6100/66 called the Power Macintosh 6100 DOS Compatible. This version came with a PDS compatibility card with an Intel 80486 DX2/66 processor (without L2 cache) and a single SIMM RAM slot that uses the same type of RAM as in the 6100 itself. The card supported up to 32 MB of RAM, a Creative Technology Vibra 16 sound chipset, and also included standard PC VGA and joystick ports. With this card, the 6100 is capable of running both the Mac OS interface and DOS/Windows 3.1 side-by-side, even on different monitors. The card could also use the main system RAM if there was no SIMM installed on the card. Notable were the new startup and "sad Mac" chimes: instead of the electronic "chuff" that was used on the previous generation machines, it
