Help needed with a IBM PCjr.
 
The IBM PCjr has a RAM card plugged into the only card slot on the
mother-board next to the Power Supply Card.  Does anyone know the
Signal names (function) of the I/O pins on this memory card. I am
trying to support a local school which has a raft of these machines and
I would like to figure out how to enhance the memory to 640 KB Ram to try
to make them a little more usefull for the students.
 
If anyone has knowledge of an existing upgrade product, or has done such
an upgrade, please advise.
 
Any help would be greatly appreciated.  Please E-Mail to address below.
 
Thank You,
Erv
