His web page on it has a link to http://www.dirtypcbs.com/ with ultra cheap boards. I wonder how their quality is.
I'm quite happy with them. In addition to the photos and my "diary" of my experience with dirtypcbs.com on this page , I made a second order from them about five months ago, and you ...

I wouldn't expect it to be a problem at any distance on a cable with a controlled impedance, assuming the voltage drop over the length of the cable isn't an issue and it is properly terminated with the same impedance at the end. I have no idea how it ever got the "it can only go 50 feet" reputation ...

I know from application experience that 115.2Kbps is readily achievable on CAT5 UTP cable over a distance of 325 feet.

I've been asked to come link this post into this thread. Of course, since anyone can drop a link, I suppose there's also an implied request that I post more than just the link. So, let's see...

Can anyone comment on whether a common, inexpensive USB serial port is an effective substitute for a ...

All these home-brew project have strange or unacceptable prerequisites.
One cause of that is that, outside of the now non-existent parallel port, there aren't many means to communicate data with a PC that don't require the other end of that communication to be already programmed in some way. So it ...

I was thinking of maybe putting together a design that people can build, but I'm never going to do that. So, for whatever it's worth, here's a picture and the files for the programmer I built:

It would be interesting if this information also applys to the ATF2500.

At the very least, the pin-out is going to be different, but I suspect a lot of the process would be similar. I've also built programmers for the AT89S52 and for the AVR series of chips (ATtiny48, ATmega328, etc.), and ...

I know what's going to be in my next electronic parts order. (-:

Do let me know if you have any problems following my instructions. While I've proofread them several times, the number of times I "corrected" my description of pins 4 through 9 before finally describing them correctly (at least I ...

I asked about how to program the ATF22V10C on reddit a couple of weeks ago, and was told no less than 3 times by someone named "Linker3000" that I should come over here. So, here I am.

With his help I found some information that gave me false hope that I knew how to program the chip. I wouldn't ...
