I misinterpreted what you wrote to mean that the memory cards
would support 1, 2, or 4 meg simms not the number of simm
slots you had on your card.  My board has 4 simm slots so I would
guess that it must be a 4 meg card.  The computer seems to be
working okay with the 4 1-meg simms I have.  I have a second
card for my other IIgs that only has two simms installed and was
trying to find another two to work.  Why don't two chip simms
work on the IIgs?  Together that brings my main machine up
to 5 meg (ROM 3).  I guess that is sufficient for most apps right?
