I need to field program some PIC 16F877's via low voltage programming in/out portc.6 and portc.7. I can do this no trouble with my desktop WIN32 and the MeLabs Bootloader which works a treat on WIN32 but MeLabs does not support WIN3.1. The only laptop I have available for this task is an old HP OmniBook 300 that has WIN 3.1 in ROM. Does anyone have some direct experience with bootloaders and older windows versions? cheers Brian -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
