The Power Macintosh 6100 was the low end member of the initial Power Macintosh family, introduced in 1994, alongside the 7100 and 8100. These machines all have PowerPC 601 processors and internal expansion via 601 PDS and NuBus slots.

The family includes Power Macintosh models with A/V and DOS Compatible versions, Performas and some Work Group Servers.

Common Specs



The 6100 has a mostly standard complement of beige Mac ports, minus the unique HDI-45 port used for the AudioVision monitor.

  • Audio Input (PlainTalk)
  • Audio Output
  • ADB
  • Two serial ports (RS422, LocalTalk, GeoPort)
  • DB25 SCSI
  • HDI-45 graphics output (the systems originally included an adapter to DA-15)


The Power Macintosh 6100 onboard graphics allocates 640 kilobytes of system memory to a graphics output that can achieve up to 832×624 resolution at 256 colors, via an HDI-45 port, which can connect to an adapter to a normal Macintosh DA-15 connector, or to the Apple AudioVision 14 display.

Internal Expansion

The 6100 has one externally accessible 5.25-inch storage bay, commonly filled with a CD-ROM drive, and one PowerPC PDS slot, typically accompanied by a riser to accomodate either one 7-inch NuBus slot or PDS cards such as those used by the 7100 and 8100.

The stock options for this slot include a DOS compatibility card known as Houdini 2 and in AV models, a card with a 2-megabyte graphics adapter and analog video input and output.

  • Steven Kan has an excellent site covering most if not all aspects of 6100 hardware and software at the 6100 Upgrade Guide


The 6100 isn't a low end machine per se, it was just the low end of the introductory PowerPC family. Apple introduced new 68k models after these were introduced, and so in total it stood close to the middle of the Mac family.

The 6100 nominally replaced the 475, 605, 610, and 660, but none of those models was discontinued upon its introduction.

The 610 was discontinued close to the time the 630 was introduced, later on in the year, and the 475/605/660 were mostly discontinued at that point.

The 630 is cited as being a replacement for the 650 as well, but the 7100 would be the more direct successor to the 650.
