Hello, I need a DSD interface card to fit the PDP-8. AFIK it should look like this <http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5177260665>. I have several other DSD cards including quad width and double width cards for the PDP-11 and LSI-11 and I will swap any of them for the PDP-8 card and I will toss in an original DSD 440 manual and DSD binder.
