I have a Rev 4 PICStart Plus that I'd like to do the Flash mod for (UK003010 module). $US29 Digikey and elsewhere. The Microchip site says that "some" PICStarts Rev 4 and before have the dreaded death problem with this module and some don't. Presumably there's some known reason for this problem. The Microchip site says that http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1406&dDocName=en010069&part=UK003010 they will replace for free any PICStart Plus Rev4 or before that has problems with this module. As I'm out at the edge of the universe, is there any easy way to tell in advance if I'll have the problem, or do I just buy it, try it and then dance the appropriate dances to get it to actually get replaced when it (invariably) turns out to be faulty? Anyone with a Rev 4 or before PICStart Plus who didn't have problems with this upgrade.
