Be careful, because even the low-profile drives APS is selling aren't compatable with your IIsi, because they draw too much power. They may even void your warranty if you install them. This applies to the Quantum ProdDrive LPS-52 and the LPS-105, and the Maxtor low-profile drives as well. The 40 and 80 megabyte low-profile drives that Quantum supplies to Apple *do* meet spec because of some modification that reduces seek time, and thus power consumption (are these drives essentially the same as the 52 and 105 megabyte drives, with 20% of them unused to reduce seek time? Sort of like how a Wren Runner gets its speed boost?) See the Page 1 article in the 12/18/90 MacWeek for more details. -- Steve Kanefsky kanefsky@cs.umn.edu
