It's a printer cable for a model 1000. I looked
through the cables I have,
and I found 3x 22-222, and 2x 22-1259. They look identical, but based on
the information I found in the Tandy 1000-series FAQ they are made for
different printers. Theres no way that I know of to identify this cable
without pinning it out. 
        The printer cable I have with my 1000HX has a yellow band on
it with Tandy p/n 26-289.  This is the cable for IBM-style printer
interfaces, vice Tandy interfaces which used p/n 22-222, among
others.  The following links go to Tandy documents talking about the
choice of printer cables:

        The cables are for the 1000-series, except for the RL, RLX, and TL/3.
