Thanks! I did not know about this problem with the year. This vintage
of mac sets the year to 1956.

Yes, the battery is dead. It is one of those $20 1/3 AA lithium cells.
I can't afford to replace it. I went into the MacOS Classic date
control panel and set the year to 1971 and it worked!

Thanks for the tip. I would have never figured this one out!
