I am running Win95 and I have downloaded the datasheet for the 16F84 a while ago, and it *did* help me understand the part better...well, a little better. Thanks to Don @ dontronics: I have been to your site briefly but didn't know what I was looking for...I do now! I'm not too worried about starting out with the Basic stamp or its derivatives...are the PIC BASIC compilers going to work with the '84 directly through the programmer, or is that just for the Basic Stamp? Thanks again. Aaron
