Dear Group: I would like to know if anyone has experience with PBASIC or other compilers (especially cheap (good) ones) that will target the 12C5XX. How much difference is there between the F84 and the 5XX. I take it there is no F version in the works on this series... Thanks and Regards, Kris Custom Solutions ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
