I have three Seagate 18GB ST318404LC drives and two Fujitsu 36GB MAJ3364MC drives, all SCA (80-pin.) Pulled from a server I just retired, wiped and tested. Yours for the cost of shipping. No takers by this weekend and they go to the dump (or get disassembled for fun, whichever I have time for.)
I do not have any adapters for these drives.
