ok here is the guy that i was buying my SCA to 50 pin adaptors from…

http://www.ebay.com/itm/SCA-80-ADAPTER-TO-68-PIN-ULTRA-SCSI-II-III-LVD-SE-C-/280498842646?pt=US_Drive_Cables_dapters&hash=item414f08ac16

i see he is selling a SCA adaptor for the same price… 1.61 but…. its SCA, but not to 50 pin scsi.

i cannot find SCA connectors for sale anywhere on the net.

maybe you will have to break down and make some calls to some factories in china….
