Well, Amiga programs SHOULD use the GetCC() function, as they also SHOULD be compatible with 68020/68030 cards. I am still pretty sure a few will fail. If I could switch back easily to a pure 68000 , that would be ok, but having to change the chips is a bit too hasardous, IMHO, for a slight 10% gain. Anyway, I should be glad to hear from those who tried. -- ============================================================================= Jean-Marc Tanzi | Millions of years to make oil and forests, jmt@cma.cma.fr | a century to burn them.
