It looks like what you have here is 1/2 of an SDI adapter.
Now the next question: what is SDI? I'll assume for now that is was an early
approximation to SCSI, something proprietary to DEC.
Nice card ejectors though -- I need a set for a recently purchased S-box
KDJ11-SD.

Hi,
This guy is auctioning a:
Vax QBUS KDA50 Disk Ctl (M7165)
http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=1240600239
What sort of interface is this? It almost looks SMD.
Guess it isn't, also rule out SCSI and MFM, by appearances.
Standard disflamer: This is Not my auction.
