- Someone suggested to me that it might be feasible to accelerate an
- A3000 much more inexpensively than with an '040 board, by hacking a
- 50 mHz CPU onto the motherboard. My question is, does anybody have
- some knowledge, or at least some well-informed speculation, on (a)
- how feasible this is, and (b) how much performance boost one would
- get? Somehow I doubt it would really speed things up much, since the
- memory can't go much faster than it does now. I think someone said
- one can change the 80ns zips for 70ns and cut out a wait state when
- using an '040 board, but beyond that Ramsey won't go. So memory
- intensive apps might only speed up by a third, maybe, instead of
- doubling in speed?
-
- Other possibility -- is Motorola yet making, or RSN making, cheap
- '040s without floating point? Might such become available in cheap
- accelerators with three digit prices? Would it be at all possible to
- use the motherboard FPU for occasional floating point while using an
- add-on board for the regular CPU?
