The 6100/60 was the low end model of the original Power Macintosh family. Released in March of 1994 the machine proved quite popular and sold well. It sported the first of the new family of processors that Apple was migrating towards, the PowerPC (a 601 chip running at 60Mhz). It came with 8MB of RAM soldered to the motherboard and the ability to add 64MB more into two RAM slots (it may be possible to add more RAM but Apple officially supports only 72MB). RAM must be added in similar sized pairs. There is a slot for L2 cache though the original version of the machine shipped without any. Adding a 1024K of L2 cache can boost processor  performance up to 50% and video performance up to 90%. The 6100 shipped without any graphics memory and used 640K of regular memory as memory for video. A large L2 cache will allow graphics memory allocation to be held in the cache thus boosting video performance significantly. The machine has one 7" PDS slot that can accommodate an Intel processor for running Windows applications or a regular processor upgrade. The 6100 came in models with and without a CD ROM drive and AV capability. Nine months after it's release the 6100 received a speed bump to 66Mhz.
