- Well, theoretically, no. See, the point isn't to make the 3000 AGA
- compatible, that won't work. Not in the way of looking EXACTLY like
- the 4000's map. But it COULD be done.
-
- One could take the Lisa and Alice and put them onto a card. Place two
- megabytes of 60ns page mode chip ram onto that bus. Put logic into
- the system so that the RGA bus signals to other processors get eaten
- (which shouldn't happen, but just in case, perhaps). Leave audio
- hardware as-is, and the old chipset is still there for audio
- processing with the Agnes/Paula pair. The RGA bus is left in tact on
- the main bus, and a new graphics display exists as a ZorroIII card.
- Now all one must do is write a graphics device for the retargetable
- graphics library said to be due for 4.0.
-
- Instant AGA graphics compatibility, as long as you're using OS
- functions. One could probably even map the blitter calls, but that's
- not the point. RTG enables ANY graphics device to work, and the AGA
- card would be one of those devices.

- Not really, not with RTG.
