PIC16F88 programing under Linux

I spent all this past week trying to program this 16F88 PIC for the APRS TNC by Bob Ball - WB8WGA. Well, not all the week but a considerable amount of time. Luckily for me I decided to test the programmer circuits in a rapid prototyping board instead of soldering. I think I tested 4 different schematics and 3 diferent software programmers. Here's what worked for me:

Schematic (external link image):
The dash lines are not connected in my prototype and it's a 16F88 pic in place.

Prototype board with pic in place:


PIC programmer in action:


Piklab version is: 0.15.0
Configuration is: JDM classic (delay 20)

Will probably make a more permanent programmer (in a PCB) but for now it's ok like this, I just needed 1 pic programed.

Now I already have the PIC in place on the APRS TNC PCB and look's that is working good, I have the command prompt and can issue commands! Unfortunately the shack computer is not working well so will test live reception in the near future, probably transmission also.

Hello Ed,
No problem with the comment in the previous post.
I managed to program also the 16F84 with this hardware (JDM) using Piklab. I am sure the 16F628 would be possible also since with my last hardware (kind of serial direct) I programed both the 84 and 628 although under picprog.
