The Power Macintosh 7500/100 was one of the machines of the second wave of PowerMacs. It was considered a mid-level machine and was part of the group of computers which comprised the 7200 at the low end and the 8500 and 9500 at the high end. The 7500 sports a 601 PowerPC processor clocked at 100Mhz. The 601 processor is relatively slow and was already outclassed by other processors at the time of its use in this machine. The 601 was abandoned with the next generation of PowerMacs. The 7500's processor resides on a separate daughter card making it easily upgradable to a faster processor. The 7500 was a very popular machine and one of the first to offer such easy upgradability. The machine is easy to get into and sports 3 PCI slots, an extra drive bay and 8 memory slots for a total possible capacity of 512MB of RAM. The 7500 shipped with 2MB of video RAM and the ability to add 2 more and also with an empty slot for installing an optional L2 cache. Adding a 512K L2 cache should gain you an approximately 18% processor speed improvement, although finding one that works properly in the 7500 has proved a problem for some owners. Make sure that the cache you are considering buying is guaranteed to work properly in your machine.
