two reasons, i'm using PBP244 at this moment and acording to the manual their are two ways of doing interupts...
in PBP using ONINTERUPT which then causes latency in the program...

The other is in assembler and every time i read it i get a headach and don't understand it... It's alien compaired to what i'm used to...

I do plan to buy the pbp260 upgrade in 2-3 weeks... perhaps that will help
