[GreenKeys] Teletype ribbon reverse

[Duncan Brown]

To be clear, all teletypewriters made by Teletype Corp (at least M28 & 
older) use an eyelet near the end of the ribbon to push an arm next to 
the ribbon spool to reverse.  If your ribbon doesn't have a eyelet, just 
tie a knot in the end of the ribbon - works fine!

Teletypewriters made by Kleinschmidt for the military (eg TT-4, TT-98, 
TT-76, etc) had a special ribbon spool with a hole on the inside where 
an arm sensed lack of ribbon. Since these ribbon spool assys are no 
longer available, you must keep the old Kleinschmidt spool and wind a 
new ribbon on to it.

Have fun,
