Adds Envoy portable Terminal

This is essentially a portable Adds 580 terminal.  It does have a builtin accoustic coupler, which probably works with 110 and 300 baud 103 dialup modem protocols.

Since this has been around the LA area for probably 40 years, it is interesting that the filter material on the back isn't powdered.  I will remove and replace it.

As nice a specimen of this terminal as I've seen.



  1. Hi , is there any possible that I can buy this terminal ??

  2. Sorry this is an extremely rare unit. I was luck to replace one I had which was stolen.

    Also this unit is the equivalent of the Adds 580 terminal in function and other than a laptop with a serial port and program it's the only actual Adds I have remaining.
