[GreenKeys] TT299B KSR

[N4BE_Jim]

Greetings!  New to the group but not to TTY.  Once (40 years ago) I operated Model 19 and 28 on MARS.  So I know about 60ma current loops etc.  But I got away from RTTY over the years, but now getting back in.  Yes I have all the usual sound card based stuff.  But I need the smell of oil, so I just acquired a TT299B "Mite" to go with a newly acquired Hal ST-8000.  A couple of questions:  is there a source of user/maintenance manuals for the Mite?  And... Is the Mite driven By a current loop, or is it a new electronic interface such as TTL or RS-232?

Thanks,
Jim N4BE
