I have seen this discussed already here: http://geekhack.org/index.php?topic=36485.0 I just pulled the switches off of a WYSE terminal board with a manufacture date of March 1996. I found three distinct logos on the switch housings.According to the linked thread above (and the other threads referenced in it), The switches on Row 1 in the pic below are the newer switches and the Row 2 switches are "vintage". So what is Row 3? I thought these were vintage at first since they were obviously different from the top aligned, small font logo said to be found on newer MX Blacks (see linked thread above). But note the smaller, less distinct logo and the beveled edge around the hole for the stem. I staged three of each switch type in rows for the pics:Is the switch in Row 3 "vintage" or not? Anyone know? There were only 6 of the Row 1 switches on this board. The rest were approximately 60% of Row 3 type and 40% Row 2 type. The board is a new in package WYSE 840366-01 WY85 Gate Array terminal board. I'd like to know because I have more of these boards to desolder and I don't want to mislabel the switches.As near as I can tell, Row 1 looks just like the newer switches and Row 2 looks just like the "vintage" switches described in the linked thread above. I just don't know what to do with the Row 3 switches. Any help would be greatly appreciated.Edit: I wanted to add that the bevel on the Row 3 switches is shiny and you can see it by rotating the switch under a good light. This is what jumped out at me first. You can see it in some of these shots as the flash is reflecting off of it.More pics:
