| Subject: | 680xx cpu/fpu speed |
Hello All,
I want to get max performance out of my A1200for internet and graphics.
Seems prob is AGA set is slow + many things rely on chip mem and ignore 32mb
of fast ram.
I have Apollo 1232........... /030 Accelerator NO FPU have mmu but try
options like copyback, virtual..........nothing seems to happen.
CPU CACHE BURST is required and apparently is accepted and implemented - but
how do I know?
Doc with accelerator says FPU required is Motorola MC68882FN40A (PLCC
package) says should be ok at 50mhz.......does this mean it NEEDS 50 mhz or
ok uo to 50mhz?
I intend to get a FPU but how can I check whether CPU is
25.........40.......or 50mhz?
(Not towered so 68040 or 60 seem not suitable accell to get) i.e. stuck
with 030:-(
also cash not abundant!! tell me your hard luck story :-)
Before lashing out for FPU I would like to be clear what involved and
improvements to expect.
Got FBlit (3.26..?) from Aminet - no docs - how use it ??? and is it as
good as some posts on this list have implied ?
I would be grateful (not quite eternally !) for any advice on how to speed
thing up.

know about fast ram.
