If the 28 pin PICs like 16F876 and 18F252 are sufficient, then it sounds like you are describing my QuickProto-01, http://www.embedinc.com/products. I'd be interested to hear if you think the QuickProto-01 is what you are looking for other than it's for 28 pin PICs instead of the 40 pin PICs. ****************************************************************** Embed Inc, Littleton Massachusetts, (978) 742-9014. #1 PIC consultant in 2004 program year. http://www.embedinc.com/products -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
