Apple Powermac 7100/80mHz AV Computer

The 7100 was the middle of the new PowerMac (PowerPC) range, boasting better performance and features than the 6100 but still a little way behind the top-of-the-line Power Mac 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.

Specs:

The Apple Power Macintosh 7100/80, based on the Carl Sagan (BHA, LAW) architecture, features a 80 MHz PowerPC 601 processor, 8 MB or 16 MB of RAM (expandable to 136Mb), and a 250 MB or 500 MB hard drive in a high-profile desktop case. 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 was available, and four expansion slots (in stark contrast to the 6100′s single NuBus PDS slot) were included.

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 Audio-Visual expansion card also added S-video and RCA video input/output.

Ports:

This model has both HDI-45 and DB-15 ports for video out as well as S-video and RCA. It included two Geoport serial ports standard (one printer, one modem). 1 x AAUI-15 Ethernet standard. S-video and RCA input/output ports provided by pre-installed AV card. Single microphone sound in port. Single rear-mounted sound out port. Finally, the usual SCSI (DB-25) and Apple Desktop Bus (ADB) keyboard & mouse port.

Video & Graphics:

By default, this model has an AV card that has 2 MB of VRAM soldered. The system has an HDI-45 port onboard that can use 640k of system memory and a DB-15 port via video card. The video card also provides S-video and RCA input/output ports.

This model supports one display via the HDI-45 port and another via the DB-15 port. The HDI-45 port uses 640k of system memory and supports a display at 512×394 or 640×480 at 16-bit or 832×624 at 8-bit. The DB-15 port uses the 2 MB of VRAM on the AV card to support a display at 512×384, 640×480 or 832×624 at 24-bit and 1024×768 or 1152×870 at 16-bit.

Supported OS:

The Powermac 7100/80mHz was originall shipped with System 7.1.2 (which included a PowerPC enabler).  Later operating systems, right through the classic range were supported including OS 8.6 and OS 9.1. Mac OS X is not supported by the first generation PowerPC architecture.
