indeed look like a 60, but I think the 55 and 35
look similar. Had it been a 50 or a 100, it would have been a
more obvious identification. 
 I have a wyse 50 (I know it is, cause the case says so). I have tried it
 in place of this dead one, and it didn't work. I don't know how different
 each model is from one another, but maybe since the 50 didn't work, I can
 rule out a 55? 
Probably not.  If the daughtercard is indeed an RS422 interface, as someone
suggested, an ordinary RS232 or RS423 terminal will probably not work.
 RS232 and 423 are single-ended interfaces, which means that each signal
consists of one wire plus a common ground connection.  RS422 is a
differential system, where each signal has a positive and negative
connection.  If your system is intended to connect to an RS422 terminal,
you'd need to do some hardware hacking to make it work.  Do you have any
information on the pinout of the interface?
