have you installed FBlit, Happyenv etc etc

are you using MMU tools to put ROM into FastRAM ? mapROM is the tool you
need for that. it'll help

up to 50MHz... you'd be best to sync the speeds up.
as for speed, what do you get reported when you type
'cpu'
from a shell? Have you tried tools like AIBB and SysSpeed?

an 060 card will happily go into a desktop. It actually generates LESS heat
than a 50MHz 030.

only stuff that uses Maths. you can get patches for the OS math libraries to
use your FPU. helps JPG datatypes quite a bit!

no docs? Are you serious? more like no icons for the docs ;-) perhaps I'm
wrong...i dont use FBlit (latest version is on AmigaOS3.5 CD IIRC

that version is horrible...why not get the OS3.1 bundle from Eyetech for a
handful of cash? Includes V4.x

OS3.1 has a LOT of gfx optimizations, bug fixes and speedups.

snap :-)
