[GreenKeys] Fw: New Introduction

[Nico de Jong]

Hello All

For the danish data museum, I'm presently trying to revive a teleprinter 
called GNT, type 15. It has built-in puncher and tape reader.
It seems to come from the danish telex network, as it has been type approved 
by the PTT. My guess is that the connections are identical to Siemens, as 
there are 8 cables with the same colors as used by Siemens. Furthermore, I 
can measure about 200 ohm across 2 combinations. What I cannot guess, is 
whether it is a 20 or 40 mA machine. Siemens uses 40. What could happen if I 
press 40 mA through a 20 mA machine ?
