I was browsing at Mouser, and noticed there are several listings for the max232... which one is the most suitable for programming, or is there any real differenc? I'm looking at building a simple rib for my GP300, but wouldn't want to order the wrong one...

I think the differences are the package styles and the temperature specs.

I would say you would want the DIP package,
Texas Instruments lists this as style "N".

I have the latest Mouser cat. here but didn't find much info on the MAX232 in it,
so I went to the Texas Instruments site and looked it up.

If you can find them, the MAX233CPP is a good one. I found a few and made up some real simple programmers for my kenwood/vertex/johnson radios. All you need is the chip, 7805 regulator, I think a 10uF electrolytic cap, and some protoboard. The nice thing about the 233CPP is that all the capacitors are internal, only a few jumpers to enable them. That plus lines in/out, 5V and ground and away you go. Good luck, Will
