M800 and M810 memory card:
==========================

Either of these memory cards may be used on this motherboard to allow 4MB or 8MB to be
added to the memory already installed on the motherboard.  There are eight SIMM sockets
on the memory card (two banks of 4 sockets), that will accept only 1Mx9 SIMMs.  There
are no switches or jumpers on the M800 or M810 to set.
