[Thinkpad] hard drive adapter

[dyllan dominque]

I have a IBM Thinkpad 390X that does not have a hard drive. The major issue
with that is that it does not have that little black 44 pin female IDC -->
44 pin ____ IBM connector. I have searched everywhere (including this
mailing list's archives) to figure out what that part/connector is called.
Can someone please fill me in on what the part is call, and if possible
where I can buy one? I have taken another Thinkpad apart, and I have what I
believe is the same connector (the 390X isn't here unfortunately) and it is
labelled "AMP 00 23 51" (which of course doesn't bring anything up in any of
my searches).

thanks!
