RAM Errors

["MechCD" <vg>]

I finally decided to try out my "new" Apple IIe I pulled from the school's
dumpster in June. It's in physically better shape than my other non working
Apple IIe.

I fired it up, and it beeps, shows the Apple ][ title, and attempts to boot
from the duodrive. I tried a few disks and it started barfing errors at me.
I tried the built-in test and it shows:

RAM: F13 F2 F11 F10 F9 F8 F7 F6

It doesn't show colors or patterns except for a small broken vertical line
before giving that message. I recall my other IIe's showing color blocks and
patterns before saying System OK.

I'm guesing I have quite a few bad RAM chips. Since its a series of chips,
could it be possible that another chip somewhere is causing this? I have an
entire working IIe board to steal chips from, but I'd rather not replace all
the ram chips if something else is the cause.

If it weren't for the physical condition, I would simply move the power
supply from this dead ram one to the other working one that has no PSU.
