I have cribbed most of these images from all around the internet; test eqipment resellers, eBay, USENET, and more. If you see an image that is "yours" in some way, and would like it removed, please email me and I will do so immediately. No infringement of anyones' copyright is intended or implied. Note that you can click the thumbnails below for higher-res images!
Conversely, these are the best images I could find of the modules. As I acquire more, I will take higher quality pictures. If you would like to "donate" high-res images, I would be most appreciative (and will of course give credit). I have found a dearth of TM500 information of the internet, and what follows is the result of detective work. Again, if you see something amiss, please let me know!
This index is not to be viewed as exhaustive, or even correct; look out below! More info is forthcoming; this is a first-pass effort to get a list online. I don't own many of these modules, so data below is mostly scavenged, inferred, or otherwise secondhand. I don't have any modules, parts, or manuals to sell, nor can I tell you where to get these.
You should also note that two separate color schemes were used over the product lifecycle. One had a dark bar at the top of the plugin, where the name appears; the other did not. More detailed info to appear soon.

Microwave Comb Generator
AKA 067-0885-00
A calibration fixture for microwave spectrum analyzers. It consists of a signal source, a coaxial cable, and a comb generator module. The output of signal source is applied to comb generator module via the coaxial cable. The 500 MHz signal source can be frequency or pulse-modulated externally. When the output of signal source is applied to the comb generator, a comb line (spectrum) of markers is generated, which are harmonics of fundamental 500 MHz. The crystal controlled source provides an accurate reference to check frequency readout accuracies up to 20 GHz. (from eBay)
Also: see this image of the spectrum generated.
