I'm just silently following along. I have never heard of that model before you guys mentioned it. I too would like to see pictures. Jason TFers, Further to Kit's post a week or two back, we've started to make some ground regarding understanding and using these excellent little GPSDO units.

Gents, I first noticed the Z3815A in January 2004 on eBay. I captured some pictures then. Moments ago I posted them here: http://www.realhamradio.com/z3815/z3815.gif http://www.realhamradio.com/z3815/z3815-front.gif http://www.realhamradio.com/z3815/z3815-rear.gif Bill, K8CU

I was thinking that myself, but this connector has four rows, and the VME only has three. (There's also P1 and P2). VXI is similar to VME. Having just worked on a project with VME cards, I know that those connectors are quite expensive. These are similar but unique, so I can't imagine the cost
