-
- Well, another stupid thing about Akiko is that it also holds equalents to both
- the 8520's, but all i/o ports are not let out of the chip case, which means
- that you still must have two standard 8520 also to get the paralell port,
- disk control signals and other such stuff...
-
- Why didn't they implement c2p in denise, an ugly but easy to bulid way
- would just be to bypass the shift registers for each bitplane, and instead
- display the byte in each of the 8 bitplanes as a chunky pixel. That would
- make the memory map for the gfx a bit ugly, each memory area which usualy
- hold one bitplane, would instead hold every eighth chunky pixel, you wuld
- then need to do some bit-rotating of the x-pointer, but it would anyway
- be a great improvement, for the cost of eight 'one of nine' multiplexers
- (all this could easyli be implemented in a 5$ pal ic, if only you could rip
- up denise and get the signals inside it). Sorry for forgetting what the
- chip realy is named in aga, so i used the ecs/ocs name denise...
