And C-A will be taking steps to rectify at least some of this in 1.4. The May/June '88 AmigaMail talks about how the exception base location may be changed on a 68010 or higher system and shows how to locate it. It mentions that serial I/O will be one of the prime beneficiaries... does anyone know what kind of speedup might be expected? Would this speedup be more noticeable at higher baud rates? (I may go 9600 baud in the new year.) Most developers may have remembered about the exception vectors, but a little reminder never hurts.
