[GreenKeys] Model 15 kbd

[Joe Stevens]

Jim, That explains a few things...  I think somebody sent me the 
wrong keyboard for the machine.  I'll bet the whole machine is NOT WU 
because it is printing perfectly from a 7.42 TD.  Thanks for that info.

I'll explore the machine a bit further, meanwhile...

Does anybody want a WU keyboard?  Trade for a 7.42 keyboard?
