I recently acquired a Macintosh Classic which is in quite good condition, but had a few questions concerning it. (FYI, I have the original System 6.0.7. Startup and System Additions floppies.) 1) When I first boot it up, and I have the Startup disk in the drive, it just sits on the grey screen with a movable cursor. However, if I do the Command+Shift+Option+Delete key combo it goes to the Happy Mac and continues to the desktop as normal. I was wondering if there's a reason it doesn't automatically go to the Happy Mac even though it's the original startup disk? My guess is that it might not have a hard disk installed in it? I do have a T-15 coming sometime soon so I can open the case and check if that is the issue. 2) I wasn't sure how to even install the HDD in the first place? From what I gathered, I need a 50 pin SCSI drive (which I have a working/compatible spare that I got recently, just not installed in anything) and a Disk Tools floppy (which I can't find the disk image for online?) and I'm not sure what else to do? 3) If there's a way to format a PC floppy (WinXP) to my Mac's format using software or otherwise.
