TEK 4107 emulators?

[mnelson at vmsa.cf.uci.edu]

      Does anybody out there in net-land know of a xterm-type 
      application which supports TEK 4107 emulation?  I am trying
      to port a program from a VAX/VMS system (using a TEK 4107)
      to a DECStation 3100 and would like to use to 'old' version
      on the DECStation until the port is completed.

      thanx in advance,

      matt
