[GreenKeys] More LXD tape reader

[Nick England]

Teletype made hundreds of variants of basic assemblies such as the LXD. So
how do you tell the difference between an LXD6 and LXD7 for example?
The Analysis Chart !

Fortunately Jim Haynes rescued a few of these rare beasts. Unfortunately
the LXD one is among the missing.
So your best chance is finding a wiring diagram that includes LXD7 along
with other variants. It might include a note about the transmitter box.
Sometimes the parts manual will include differences.

More later today.
