DD50 SCSI connector

I went into Radio Shack to get a soldering iron tip a few weeks ago, only to
find that they've finally started putting industry standard part numbers on
their blister-packed stuff. What a surprise to find not 239-???? but a
package that actually reflected the part number we're used to, e.g. 74LS367
and such.

Maybe that will take the pressure to learn what it is they're selling off
the help.
