Not really. First, this is a new part and the errata applies to the "ES" version. This stands for engineering samples. Such early versions often have a few strange problems. Unless you are reasonably well connected, you'll never see an ES chip. Seconds, if you've got enough expertise with PICs and electronics to get ES parts, modifying a programmer produce 3V power instead of 5V shouldn't be a big deal for you. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
