- How do people design Memory Expansion Boards for the Amiga?
- Do the boards autoposition themselves ie have dynamic lower
- and upper address limits? Because what I would like to build
- entirely for personal enjoyment at this time is a ROM
- expansion board. Where I hope to be able to put some custom
- software that I have written into these ROM chips and not
- 'waste' any RAM space.
- Dealing with the same topic but for the Amiga 1200. I have
- heard that the A1200 has a maximum addresseable window for
- RAM of 10 MBytes. Would this mean I could put ROMs in higher
- ram than 10 MBytes or would it mean just the opposite? Any
- references to Hardware Reference manuals is appreciated.
