What is the pin spacing on the edge 5200a connector? BTW, I got in my circuit boards for the TM500/5000 and HP5370 extenders from China. They look great. I am now waiting for the rest of the edge connectors to arrive. They have been shipped... from the US. Should be here in a day or two. I built up three of the TM500 cables and a GPIB extender cable. They work very well. Just for fun, I tried running a few TM500 and TM5000 modules with 8 foot long extender cables... no problems seen.
