[GreenKeys] Anyone on here know about the AT&T 5310 printer line?

[Jim Haynes]

Yeah, I got one of those 5310T units also.  But have not made any use
of it.  The 5310 given me by the former Teletype guy seems to be the
keyboardless model intended for use as a printer with a PC, as it has
a "Centronics" type of connector on the back, and no place to plug in
a keyboard.  And has some problem - when I turn it on it gives an error
code on the front display and the 5310T manual just says that any code
other than 800 means something is wrong somewhere.  So I need a maintenace
manual, if I'm going to fix it.  Which seems unlikely anyway.

The guy told me that the keyboard logic is the same as an IBM PC keyboard.
He gave me 3 keyboards, all are heavy like the old IBM keyboards.  One has
no cord, one has a cord with a DB-9 connector, and one has a cord with a
PS/2 sort of connector.  So none of them works with the 5310T, but if I
knew the connections I could make an adapter to use any IBM keyboard
with it.  Assuming he is telling the truth.  I just plugged that keyboard
into my PC and it seems to work fine, so if that's really true about the
5310s then any keyboard old enough to have the PS/2 connector should work,
with the proper connections.

But the one with the DB-9 connector has 5 pins, so I don't know if a 4-pin
modular plug is adequate.  Well I just looked at it, and it is a 6-pin
modular.  I don't know if it will be possible without a schematic to 
figure out how to wire the 5 pins of the DB-9 into the six pin modular.
