for THVP ?
pkp (cmdline part of pikdev) and broccoli18. About 2years ago when I
used 16F628 alot I used your version of picprg.
Here a a few pictures of my THVP:

I kept the cable between PC and burner short as per your recommodation.
That means I have to crawl under the desk each time I wanna burn a PIC :(
Thats a big reason why I'd like a second "more proper" USB programmer

Yes. At first I thought that JDM designs were able to cope with weak
serial ports, but I was wrong.
