Macintosh Plus Problems

I've had a Mac Plus for quite some time, and just got all the stuff to get it up and running. Only problem is, it won't run.

First concern is, most Mac Pluses I've seen have a gray background. Mine has a black background.

Second problem is when I put a System 6.0.4 disk into the Plus, I get a Happy Mac, some disk noise, and then nothing. It's hanging on the Happy Mac.

Third concern is I'm wondering if sitting in a garage for God knows how long will affect the performance of the machine.

FOURTH CONCERN!! When I boot the machine up and let the monitor bring up the picture, then quickly turn it off, I see some garbled gray stuff on the screen. Then when I quickly turn in on, I see white lines and the contents of the screen before turning it off moving up the screen, then disappearing. Is that normal?

Do I need to open this thing up and see what's going on? I'm scared to get shocked by the monitor, or breaking the monitor. HELP PLEASE! VERY APPRECIATED.

Okie dokie ..

That is just the last users choice of a back ground so .. thats probably normal. You can choose the background color using control panel.

the happy mac staying on screen is not normal...

No, Its wont effect the machine really as the are no moving parts in the machine apart from the floppy drive

And ..

Yes to see the picture last on the screen before you turned it off is normal : )

Hmmm... How long does the happy mac stay up? I would try to give it a good amount of time. I don't think its a hardware problem. You should try taking it to the apple store!
