parallel port multi pic programmer?

[SuB-ZeRo]

I have the serial converter and a JDM programmer but converter's voltage is not enough.I lower the value of the resistance but this time i am having problem writing the pic.Now i want to ask something may be one of you tryed before.In the shema u can see the JDM programmer circuit.Can we convert this circuit for parallel port?Do u think will it work?

I try all the configrations of the IC-Prog.I can't use Direct I/O when i use a RS232 converter.After than i chose the option Windows API.Still nothing!I invert the data and the others.I tryed 1 by 1 but i cant figure out any thing
And now if any body useing USB to RS232 converter and a JDM programmer What re the configrations of the IC-PROG ? Or will i have to use my desktop forever?Or if somebody has parallel port programmer for 16F628 and 16F877 i am only useing these pic's I try to make ProPic2 but i couldn't have victory I need something simple from parallel port that can program 16F628 and 16F877 thats all.Thanks for the help.

i'm reeeeeeeeeeeeeeeeeally not sure of what i say now, some can confirm. Probably you'll need to use an external power supply or have some kind of level shifter that use the USB power line to raise the voltage...

i remind a previous post somewhere here, i'll try to find it and come back with the link.

One of the best USB and/or Serial multi-pic programmer is here:
http://siscobf.webcindario.com/winpic800.htm
Schematic, .hex, drivers and software as included. And completely FREE.
Support 16Fxxx, 18Fxxxx, 24xxxx and dsPics family.
The soft is in constantly updated.
NO need for a USB converter it is done in the microcontroller.
same for power supply converter from 5vdc to 13.6vdc

PROPIC2 Clone made in Italy.

Modified version of the original PROPIC2.
!!!!! The PCB uses a female DB25. (*FEMALE*)!!!!!!
