[GreenKeys] Salvaged Bell System 28

[Larry Tighe]

Well, Jack suggested I put the mark and space of the Bell System Model 28 I 
picked up off the curb last week into the ST-8000A transmit tones.

It has 2125/2275 for W1AW on the receive side and   1070/1140 on the 
transmit side for the Bell modem 43B3 system in the base of the tty.

Worked perfectly!  The machine requires Figs H Ltrs to clear any previous 
"unblind" codes for the printer.  Then type ZA or RZ or FX and the "unblind" 
magnet frees the printer to print.

So, copied W1AW tonite and converted the input tones to the Bell tones and 
the machine copied perfectly.  I was fortunate to find lots of prints and 
flow charts inside the base of the machine.

Thaks for the ideas Jack.
