- This seems to be the net.wisdom throughout the csa groups.
- But is it necessarily true? Bandwidth doesn't seem like
- it should be a big problem. Even Dave H. mentioned that
- the choice between a 32-bit or a 16-bit double-speed custom
- chip set is an engineering decision. If one wanted to squeeze
- the AGA chipset into existing (oops, earlier - I guess the
- A4000 "exists" :-)) Amigas, couldn't you work the 16 bit
- memory a little harder to assemble 32-bit words. Perhaps
- faster memory or page-mode devices would be required, but
- that seems feasible since they could be put in the existing
- sockets. Angus/Alice is the DRAM controller, isn't it, so
- nothing should interfere with page mode accesses? Just
- wondering ...
