Apple Power Macintosh 8100/80AV M1688 Specs

The Apple Power Macintosh 8100/80AV, based on the Cold Fusion architecture, is visually similar to the Quadra 800 that it replaces.  It’s case has a steel fold over side panel with moulded plastic front secured to it. 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.

This computer was released along side the PowerMac 6100/60 AV and Power Macintosh 7100/66.  The group of 3 computers marked a significant change in direction for Apple, moving away from traditional Motrola Architecure to RISC based processors.


The Powermac 8100/80AV features an 80 MHz PowerPC 601 processor,  16 MB of RAM, and a 500 MB hard drive in an expandable tower case. The workgroup server version of this model is the Macintosh WGS 8150/80.  It, along with the PowerMac 8100/80 was the only model to ship with 256kB of level 2 Cache installed as part of the factory assembly process.
