[MRCA] AN/GSM-64

[Ray Fantini]

Picked up a bunch of stuff recently. One of the more unusual items are a couple NOS Fluke Digital Multi Meters. Think they are AN/GSM-64 but not exactly the same as that. The 64 is the military version of the Fluke 8400 series or maybe this is somehow related to the 8125 portable DMM but its not one of those. They were designed to use some weird twelve pin plug that can be connected to the front or back and had test leads or some remote box that had the input, common and the source for the Ohms function unlike the 8400 that has the banana plugs on the front for this. The internal circuit appears to be identical to the 8400 and use the same color code for the wires so was able to easily identify DC/AC input and Ohms outputs.
Thinking of removing the plug and building a plate with four banana plugs and installing where J7 currently is.
Anyone ever seen one of these before or have any idea what it was produced for? Think this is the biggest and most over built DMM that I have ever seen and may make a great addition to the work bench being it's so big, heavy and somewhat pointless compared to modern hand-held meters.
