Apple Power Mac 8100/100AV Specifications

Like it’s predecessor, the PowerMac 8100/80av, the Power Macintosh 8100/100AV is based onpowermac 8100/100mHzthe Cold Fusion architecture (aptly named after the “Cold Fusion” Hoax – a missing link perhaps?  Apple saw the original line of PowerMacs as the missing link between the 68k Mac and PowerPC architecture).

The Powermac 8100 series was released alongside the Powermac 7100 and PowerPC 6100/66av, all featuring a PowerPC 601 processor.  Case designs were all re-iterations of previously used designs and the 8100 was no exception, employing the same case as the Quadra 840av.


The Apple Power Macintosh 8100/100av features a 100 MHz PowerPC 601 processor running on a system bus speed of 33.3mHz, 8 MB or 16 MB of RAM (expandable to 264MB), a 700 MB or 1 GB hard drive, and an optional 2X CD-ROM drive. Removable front bezels indicate the 5 1/4 and 3.5 inch slots of the cdrom and floppy drive respectively and a further blanking plate that accepts a further drive.

Video & Graphics:

The Powermac 8100 used ram for video and contained both Nubus slots and a single PDS slot.  However, unlike the Quadra 800 from which it derived it’s case, the Powermac 8100′s Nubus ports will not accept 68k video cards and instead uses proprietary Nubus PowerPC cards.

The system has an HDI-45 port onboard that can use 640k of system memory and 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 PowerMac 8100 rearsupport a display at 512×384, 640×480 or 832×624 at 24-bit and 1024×768 or 1152×870 at 16-bit. The video card also provides S-video onboard and RCA input/output ports via adapter.

Ports & Connectivity:

The Powermac 8100/100mHz offered DB-25 SCSI port, AAUI Ethernet port (10 base T), Serial Geoports for Printer and Modem (8 pin mini din), ADB Port (Apple desktop bus), stereo sound out port (3.5mm jack), 3 x NUBUS expansion ports, a DB-15 Monitor port (via seperate NUBUS video card) abd a monitor power out socket. Not Shown in Image: S-video and RCA input/output ports provided by pre-installed AV card. RCA supported via provided adapter.

System Compatability:

The PowerMac 8100/100av is a member of the PowerPC family of computers.  It was shipped with Macintosh System 7.5 and can operate with systems up to and including Mac OS 9.1.  However, it can only operate with the classic environment and is not OS X compatible.
