- Yes, there are 256K and 512K ram cards available. They use a system
- called bank-switching to access all of the memory. Because the 48 can only
- handle 128K at a time (in each slot) you can only access 128k of the card at any
- given time.I'm not sure how this affects libs when you change banks. I
- personally don't have onat this time (they cost too much), and I
- find that for my purposes 1 128K card and a 128K custom ROM card are plenty. I
- guess it depends on how much you want to spend.....
