Hi, I have a near-death Mac Plus 1mb. I bought it off of eBay as-is in hopes to repair it. I have changed out the RAM so that it would start up correctly. That problem is fixed and now the computer will run start up, chime, and go to the screen with the floppy disc and the blinking '?'. As soon as I insert a disc (Mac OS 6.0.5 on DS/DD) the computer reads the disc, says 'Welcome to Macintosh' and then either restarts or hangs up. Anyone know what is going on? Any help will be appreciated, Thanks.
