My //e died. Can you help me fix it?

[drew@ctnet.com (Drew Ivan)]

I recently brought my //e out of mothballs just for fun. Despite
years of disuse, it booted up and worked fine for a week or more.
I wrote a little AppleSoft BASIC program to compute some fractal 
functions and left it running at work over the weekend. When I 
came in on Monday morning, it had blinking characters on the text
screen, and it wouldn't respond to any commands. 

I tried rebooting, which didn't work. I switched off the power and
turned it back on. It came up with "Apple ][" at the top, but the
screen was covered with blinking characters. There was a "]" prompt,
but anything you typed was a syntax error. 

I took out each card, one by one, and tried rebooting. No luck. I
took out _all_ the cards and started up. Same thing. You still
can't reboot with control-open apple-reset. I seem to remember
there being a built-in self test, but either I don't remember how
to do it or it simply won't do it. (I'm using control-both apples-
reset.)

Any clue what might be wrong or how I might fix it? Thanks.
