there are only two kinds of mac mouses: 9 pin for plus and earlier and adb for se and later models. i've never heard of anything else. as for slow booting, you might want to run disk first aid if you have it on your machine. i think you need to boot off a floppy and run it from there for it to check and fix any problems it finds. those two buttons you found is the programmer's switch. one does a reboot and the other brings you to a system monitor prompt. supposedly useful for those that know what to do. david In a message dated 98-06-24 21:43:32 EDT, megan writes: << Speaking of Mac Mice... At the MIT Flea this past weekend, I picked up a mouse for the Mac Classic I mentioned in other mail... it is the 'original' style of apple mouse. My question is whether this will work correctly with the Mac Classic -- it does seem to plug in, but since I'm not getting much response from the system, I don't know... BTW - another question -- when the Mac Classic boots, it shows the smiley disk and I hear the internal HD working. The screen goes light grey with a pointer on it. This is displayed for a few seconds and then I get the 'Welcome to Macintosh' screen. This remains this way for as much as 10 minutes (I didn't wait longer). Is this normal? Have I simply not allowed the system adequate time to boot to a user screen? (I'm used to an RT system which boots in about 30-45 seconds, depending on amount of memory). Also, there are two buttons on the left side of the case... one apparently does the mac equivalent of the three-fingered-salute on PCs... the other one causes the 'Welcome to Macintosh' screen to go away and be replaced by one which lookes the same (banner background) but with a '>' sign... What is this?
