Upgraded to the GOLD version and bought upgrade for MCS + as well. Now if I remember correctly MCS+ for PBP3 requires Vista or 7 ? and if so it pretty well cancels my need for extra seats as I still use WIN98 in the shop. I an looking hard at the " C " environment, just for portability from PICs to other platforms. I have been playing with arduinos lately and for hoots loaded a PIC hex into it with mixed results, or maybe it was the other way, cannot remember now, either way, it did not choke as bad as expected.
