I recently picked up a classic II with OS7.5 installed. From what I've read compacts such as the Classic II perform better with 7.0 then they do with 7.5. I'm thinking of rolling the Mac back to 7.0, is there any reason not to do so? The system also has Conectix Ram Doubler 2 installed. About this Mac shows 4096k of built in Ram and 12288k total. IIRC the Classic II actually has 2m of Ram built in, so I assume that the Ram Doubler is somehow tricking the system into believing it has 4 m of built in Ram. Does this mean my Classic II also has an additional 4m of ram installed? 2 megs built in + 4 megs add on *2 (RAm Doubler) = 12 megs, right? I vaguely remember having a Ram doubler in Windows 3.1, is this the same type of program?
