I'm not sure about what all of the cards are for, but the RAM card just kind of sits
there, with no visible means of support.

? Cool! Thanks for the pictures
and information. I was able to find the
power tabs labeled in the silk screen on the power supply
board. This
saves me from having to trace them down. I recognize the
floppy
controller, and the ram card in those pictures. What are
the other two
expansion cards? I also remember there being some kind of
frame that
kind of held the ram card in place, and I am not sure what
I did with
it. I don't see one on your system. Is there any kind of
mechanical
support tab or rail on the back of your ram card to hold it
in the slot?
Thanks
Shannon
