desperately seeking pertec cables

I have a TS05 tape drive with cables for a TSV05, i.e. 50 pin edge to 50 pin high density (i.e. scsi-2 connectors). I thought I had a way to connect the cables to 50 pin .1" headers (which the controller board wants) but it turns out the way the DEC TVS05 cables uses the "high density/a.k.a scsi-2" connector is not the same as the way SCSI-2 uses it - the pins don't map correctly if you use an off the shelf scsi-2/.1"header converter. This has me frustrated and an in need of some standard "pertec cables", i.e. 50 pin edge to 50 pin .1" header. (i was all set to boot off the ts05 or tm11 controller but no joy :-( Does anyone have a pair of these, at least say 10' that they don't need and would sell? -brad i'm going to go drown my sorrows in a martini :-)
