Natcherly, ProDOS-8 doesn't need the driver anyway. I don't understand: You're correct that ProDOS 8 doesn't need the AppleDisk5.25 driver, so what does this have to do with ShrinkIt 2.1 and P8? >With System Software 4.0, I found that some programs seemed to need the >UniDisk3.5 driver there also... for the 5.25 driver to operate... That's sounds very odd--it's always worked fine for me, and I've never installed the UniDisk3.5 driver (since I don't have a UniDisk 3.5). From very limited information, I'd guess that the application had a problem where it would use data in the wrong bank under certain memory configurations--in a delicate state like that, adding or removing any driver, DA, etc, can make or break the application. > but the 4.0 >version of the AppleDisk5.25 was buggy, anyway.

It bothers me a little to see anything written off as plain "buggy"--what problems are you referring to, and what is your source of information? The only problem I recall at the moment is that it returned incorrect write- protected status under some conditions. >garths@pro-xy (Garth Shultz) --Dave Lyons, Apple Computer, Inc. | DAL Systems AppleLink--Apple Edition: DAVE.LYONS | P.O.
