Actually, flexing the board while powering up, yes, and it
shows no differences. This thing will not do anything past
what I described in the first post. I also have some IIe and IIc
boards that pop up the logo screen and then display lots of
weird characters on the screen. I assume that since none of
these get past that point that there is probably a leading ram
chip gone bad. Sorry about this part, but my PC did this also
the time the first simm went. I believe I will have to remove
each ram chip one by one until I know for sure what is going
on. I can probably just grab a couple rom1 boards from eBay
but this is a Woz machine and I'd like it to stay original. Well,
I guess it's not worth the hassle, huh?
