Re: Ram Card Problem (picture)

The GS-RAM card can hold 1.5 megs of ram. Yes you can use the memory off
the Apple 1 meg card. 256k 100ns chips work fine. If you are going to use
this
GS-RAM card in a ROM3 system, you will have some problems. The GS ROM3
will think there is more memory then the card realy has.
