If you find a good source for the prototype kits, by all means, let me know. I've been gutting cheap/dead modules for the enclosures. A project I've been considering is putting a T'bolt into one just to send 1pps and 10mhz down the backplane.
BTW, there is a yahoo group for TM500/5000 series gear. Not much traffic, but it is there. http://tech.groups.yahoo.com/group/tek500/ On Thu, Sep 16, 2010 at 11:19 AM, <[email protected]> wrote: > Aha!
