My //e and IIc Messed UP start

[What Up <dede@fwi.com>]

Well when I start up my Apple //e and my IIc, they have very messed up
displays.

When I turn on the Apple //e the display is messed with white blocks (I
think it is Hi-res mode), and I have to hit Open Apple-Control-Reset a
few times before it goes to the black-white text mode then to the
booting screen.. (it's the A2 with the number pad on keyboard)

As for the Apple IIc, it has a similar situation.  I'm still trying to
get it to boot the 5.25 disk. I remember it worked the last time I used
it. My only concern would be the power supply. Yeah back when it was
warm, we were moving a lot of stuff in my S-10 pickup with a bed cover,
and then I park the truck for the winter, and forgot about it.  About 3
days ago, I wanted to hook up my IIc, and I couldn't find the power
supply, then I had a hunch it might be in the truck cab. Nope I
unsnapped the cover and found it in the bed..

Why would my systems be doing this.  They were acting fine before..
