I understand about the 3.3V. Obviously the target has 3.3V VDD and mix 
of 3V and 5V pins (many pins allow 5V pullup resistors). I can easily 
adapt a programmer for 3.3V Data, Clock and Vdd. However there is no 
point to the HW modifications unless there is Programming software that 
support "bit-bang" via RS232 handshake pins for PIC18F67J50 and PIC18F46J50.

The HW interface issue can be solved easily, if there is software. Or 
does the PICkit 2  definitely support PIC18F67J50 and PIC18F46J50. If so 
where is best place to buy it?  (Not from North America as Postage Speed 
and Price from N.A. is just plain silly to Ireland. What is 10 days & 5 
Euro postage from Singapore/Thialand/China/Hong Kong is 20 Euro postage 
and 15 to 20 days from USA. Canada seems worse)

At the moment, time is more available than money, so if Windows XP (or 
Linux) software was available for my existing programmer design adapted 
for 3.3V, then I'd prefer that route. TXD enables VPP, clock is RTS and 
Data I/O is CTS/DTR. Changing the two levels of VPP and changing, VPP, 
Data & Clock levels is trivial.
