    Default GRiDCASE 1537 - Anyone ever seen an RS-422 port like this?

    I have here a GRiDCASE 1537. An incredible machine (with an incredulous amount of shielding inside, JEEBUS!), and there is a most curious connector on the back for an RS-422 connection, I've seen a lot of different RS-422 connectors over the years, but I've never seen this guy, anyone know what the hell it was meant to interface to?

    (Given that this laptop was made explicitly for classified information processing, it's gotta be something interesting...)



    (Also, it has a SCSI host adapter inside it, going to a DB25 SCSI connector on the back, anyone have an idea how I can figure out what SCSI controller is in this thing?)

    I believe the connector is a 25 pin micro-D. https://www.digikey.com/product-deta...137-ND/2798600

    Is it possible the pinout might be something like this? http://www.ni.com/product-documentation/54543/en/
