I'm not sure how I feel about calling this "RAM Paging port", because all of 05,06, and 07 can be used to page in RAM. Personally I think that if we designate 0000-3FFF as bank0, 4000-7FFF as bank1, 8000-BFFF as bank2, and C000-FFFF as bank3 it will be the clearest. Then we can say port 5 controls bank3, port 6 controls bank1, and port 7 controls bank2. --Dan Englender 09:46, 28 Mar 2005 (PST)
- Well, does it even make sense to assign a bank number to 0000h~3FFFh, since that's permanently set as ROM Page 0? Also another option would be to just call them by the address block they effect (or at least the first address)? Eg, bankC000, bank4000, bank8000? --Aquanight 15:47, 30 Mar 2005 (PST)
I don't see why not to assign a bacnk number to 0000-3FFF. Just because the data in there isn't changing doesn't mean it's not useful to talk about it. Memory is logically split into these four different segments, so it's useful to have names for all of them. --Dan Englender 08:32, 31 Mar 2005 (PST)
