I have seen in the new MPLAB 3.40.09 readme notes that there is an upgrade to the PICSTART Plus programmer. It says that you need to program a 17C44 with the new firmware software (PSF15000.HEX ?). I have searched on Microchip's web and cannot find it - does anyone know what the procedure is? Also I have an older PICSTART-16C - can this be upgraded so that it could be recognised by MPLAB and then used to program some devices as it is a shame to waste it. thanks Stephen H Alsop, dms@ukonline.co.uk http://easyweb.easynet.co.uk/~s.ssystems
