    I am trying to use the programmer from

    http://members.aon.at/electronics/pic/picpgm/index.html

    I have built the circuit
    picpgm_cable according to the diagram. I have used a
    74LS04 instead of 74ALS05 because this is what was
    available. I then run the software WinPicPgm and on
    the status line at the bottom there is a message
    "No pic programmer found".
    Can you help me?
    thanks!!

    At a glance I found this:

    "A driver which is necessary to access the parallel port under Windows 2k/XP
    is included and loaded automatically by the programmer software (no user
    interaction necessary). "

    It seems as if your driver isn't loading, look for it in your task manager.
    Further, is your
    parallel port on 0378h or one of the other two standard addresses?

    Is your motherboard BIOS set to use the port as ECP ?

    It looks like they assume you know to connect 5 volts and ground
    to the 74ALS04...did you power the inverter? It works best when
    power is present!

    My apple pie recipe calls for apples. But I used tomatoes because
    that was what was available. How come my apple pie doesn't taste right???

    The first step in making any circuit work is to use the correct part.
    If you can't us the correct part, at least use a COMATIBLE one.
    The '04 is trashing your return data path.

    They are totally different parts, it won't work without the '05.
    The '05 is open-collector, totally different.

    Mucho snippage...
    Steve,

    I took Mike's answer as the correct one. To quote

    "My apple pie recipe calls for apples. But I used tomatoes because
    that was what was available. How come my apple pie doesn't taste right???

    The first step in making any circuit work is to use the correct part.
    If you can't us the correct part, at least use a COMATIBLE (sic) one.
    The '04 is trashing your return data path."

    That's why I didn't bother to answer.

    The guy never got back to me about the use of a PCB or anything else.
    I would have suggested some other O.C. component but I really haven't
    given it any thought.

    But only a grade of B for that.

    "But Byron, what's wrong, they're both inverters??!!"
