Alright, thanks very much. I have already built a prototype PCB. Just waiting for it to be ready. I am using a 32k on the RB6.7 so i can almost exact RT clock (actually 15sec pulse) without overloading the already overloaded Interrupt routine. I have a program that the main routine is only GOTO $ !! (for future implementation), thats why i have all my needs inside the irupt routine. I have tested this config on a protoboard, and it does not work. I have to unload RB6.7 of any external capacity.
