Power Macintosh 6100
Also available under the "Performa" and "Workgroup Server" model lines. The Power Macintosh 6100 also offered the "DOS Compatible" model which featured a 486DX2/66 on an expansion card.
The 6100/60 model can run Apple's System 7.1.2 software which is the first release of the system software capable of running on PowerPC. The minimum for the 6100/66 model is said to be System 7.5.
Available with either a 60MHz or 66MHz PowerPC 601 processor. A 256KB L2 cache upgrade is standard on the 66MHz version and was optional on the original 60MHz model.
Allows for a single expansion card, either NuBus or PDS depending which adapter is installed. Common expansion cards found in these systems:
- 486DX2/66 PC compatibility card (PDS)
- Power Macintosh AV Card 820-0510-A (PDS) - DB15 video output, S-video input/output
- Power Macintosh HPV Card (PDS) - DB15 video output, expandable VRAM
The board includes 8MB RAM and two slots for 72-pin memory. The originally documented maximum memory is 72MB via two 32MB memory sticks, though larger sizes may also work. Other sites report that you should use matched size memory modules.
Apple's DOS and Windows drivers support an Apple-compatible CD-ROM, folder sharing and clipboard sharing. Early versions of PC support software for the DOS card also included video drivers for MS-DOS applications such as AutoCAD or WordPerfect. MS-DOS and Windows are installed from the standard installation disks or CD-ROMs provided by Microsoft.
PC Setup 1.0.2: This is the last downloadable release that supports the Houdini I card. The downloadable software from Apple only includes the PC Setup control panel, so you may need to hunt around for DOS drivers or experiment with those provided with PC Setup 1.5 or 1.6.4.
PC Setup 1.5: This version supports the Houdini II and LC 630/640 cards. It runs on System 7.5.3 on the LC 630/640, or 7.1.2 and 7.5.3 on the 6100, so it is handy if you don't have much RAM for the Mac OS. DOS clipboard sharing is not supported and RAM must be installed on a Houdini 630/640 card. Open Transport is not officially supported but many people found that Open Transport 1.1.1 works. The downloadable software from Apple includes separate Mac and PC disk images.
PC Setup 1.6.4: This is the last version released by Apple and it supports all but the Houdini I card. It requires 7.5.3 and Open Transport 1.1.1, and was officially supported by Apple up to Mac OS 8.1. In spite of these restrictions, many users have used PC Setup 1.6.4 in limited fashion with Mac OS 8.5, 8.6 and 9.x (see Networking Problems below for solutions). The downloadable software from Apple includes separate Mac and PC disk images. Apple's PC drivers are still 16 bit but you may wish to try using them with earlier versions of PC Setup.
PC Setup 2.x: Apple provided technical information about DOS cards to a third party developer, Discovery Software, so that they could write 32 bit Windows drivers to improve Windows 95 and 98 performance. PC Setup 2.x includes 32 bit hard disk and CD-ROM drivers, and enhances network support. It also supports Mac OS 8.5, 8.6 and 9.x and tries to correct earlier networking problems. PC Setup 2.x is not a full installation and it is necessary to install PC Setup 1.6.4 first.
PC Setup 2.x, was sold commercially for several years. When the third party developer discontinued it, PC Setup 2.1.7, the final version, was made available as a free download. You will need three files (Mac and PC installation sets and the PDF manual). Install using the license code below:
- Authorization Code: UEV-EVZ-7TU
- License Name: FREE
- License Site: 469
- PC Setup 1.0.2
- DOS Compatibility 1.5
- PC Compatibility 1.6.4 - Disk 1, Disk 2
- Video drivers for 6100 DOS card
- If the PRAM battery is dead or missing, the computer will likely not display any video upon being powered on. Without using a new battery, you can try the "double-tap" method which is pushing the power button twice quickly and it may restore video signal.
- The PowerPC 601 CPU is extremely fragile on this board and simply installing the heatsink can crack the processor.
- Heat inside the case can be an issue, especially with the model including the 486 card. You may want to outfit a case fan somewhere inside to help move air.
- If the heatsink compound on the CPU has not been replaced since the original manufacturing, the CPU may overheat and destroy itself. It is recommended that it be cleaned and replaced.
