[GreenKeys] ASR33

[Don Robert House]

You need to contact someone else who has already done what you are  
attempting.
I no longer have any of the Classic Computer guys in my email address  
book.

I will copy a couple of men who might be able to steer you.

Guessing is not the best solution.  The smoke is hard to get back into  
the unit.

Is the ASR33 capable of generating voltage/current spikes via the 20mA
connection?  I realize the connection is passive, but what exactly is
the 20mA connection driving? Should I be concerned about connecting
the ASR33 directly to my old PDP-11's?  I am more concerned about
ensuring the PDP-11 will be ok and not as concerned if something bad
happens to the ASR33 since the TTY is much easier to fix/replace :-)

Is there any tests I could perform before hooking the TTY to my  
computer?

Many thanks for any information.
