- First of all, How does a bus work?
-
- second, 16 bits on a memory 'bus' would seem (to me) that it could
- only adress 64k. but it can adress 16megs.. or 24bits.
- would the chip send 2 bytes out in two cycles to complete an adress?
- thats screwy.
-
-
- You can add TT ram to the falcon (32 bit ram) (or so says AtariUser)
-
- third: Atari docs state full 32bits, it would be crime to lie about something
- like that.
- (of course, big corps can get away with that stuff.)
-
-
- could it be that the PDS slot could be confused with another bus?
- the pds is 16/24 68000 compatible. (according to my mags)
- its definately not 32bits
- and, its something dave small would be 'into' since he's mr. mac emulation
- (the primary purpose of the PDS slot)
-
- could a 16bit adress bus be 4-5x faster than an ST?
-
- what was the ST bus like?
- was it 16? 24?
-
- why would atari have a dsp/videl and other 'cool' stuff in the falcon, but
- then intentionally screw the cpu?
-
- i would figure its not any cheaper to have 16bit busses...
-
- just my observations.
