Power Macintosh 6100

=General Information=
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.
Introduced in March 1994, the PowerMac 6100 was the first Mac to be powered by a PowerPC processor. An optional AV configuration was available. The 6100 came in a Centris 610-style low-profile case, cost $1,700, and was "speed bumped" to 66 Mhz in January 1995. The 6100/66 was discontinued at the end of 1995. The 6100/66 DOS was also available, with a 66 Mhz 486DX/2 processor card, and was discontinued in early 1996. The 6100 was also offered bundled with a monitor and various hard drives, as the Performa 6110CD, 6112CD, 6115CD, 6116CD, 6117CD, and 6118CD.
Codename: Piltdown Man. Originally shipped with a PowerPC specific version of system software 7.1.2.
The CPU bus is the standard 64-bit nonpipelined bus used by the PowerPC 601 processor.
* 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 Power Macintosh 6100 [[NuBus]] adapter card gives the Power Macintosh 6100/60 a NuBus expansion capability. The adapter card contains the BART NuBus controller chip that is included on the main logic board of the other Power Macintosh models. It plugs into the PDS slot of the Power Macintosh 6100/60 and accepts one short (7-inch) NuBus card, which lies parallel to the main logic board.
The board includes 8MB RAM and two slots for 72-pin memory, 80ns or faster. The originally documented maximum memory is 72MB via two 32MB memory sticks, though larger sizes may also work. SIMMs must be installed in pairs of the same size and speed. Install noncomposite SIMMS only.
Power Macintosh computers contain 4 MB of ROM with 100-ns access time. Some of the system software that was on disk in previous Macintosh computers is in ROM in Power Macintosh models.
All Power Macintosh models accept an external second-level cache on a SIMM. The second-level cache size may range from 128 KB to 256 KB. The Power Macintosh 8100/80 is shipped with all 256 KB already installed; users of other models in the Power Macintosh family can install a second-level cache by plugging a SIMM into a 160-pin connector on the main logic board. The high-speed memory controller (HMC) interrogates two pins of this connector during system startup, to determine the size of the memory on the SIMM. If no SIMM is installed, pull-up resistors on these pins cause the HMC to disable all external cache operations.
