Hi Eugene, I found my Emulex boards, but found TU13s and not QT13s. I did not look at the S box boards. Then I found a few Cipher Data Products ( AKA Spectra Logic Products) 500A00s. I'm not sure what they are, but they look like re-branded Emulex with different handles. Did Dilog or anyone

You should talk to Carl as he’s created (or far along in the process) of a DSKY to interface to an actual AGC that’s being restored (there are a number of videos on-line of the restoration effort…mostly done by converting a hotel room into a lab). TTFN - Guy > On Apr 11, 2019, at 10:59 PM,
