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. mike

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

Wow! That one is way old Steve....are you just getting it?

-------------------- Nope, just finding the time to catch up is all, been too busy.

--------------- I note ALSO that nobody gave the right answer, are you guys slipping?

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.

I'm up to my butt in alligators right now too...I will be traveling 200 miles to the job site Monday at 4:30 A.M. Lets hope the phone guy is on time as they don't like me climbing their poles!

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??!!"
