One of them is a commercial product called FaceTerm, and I got the copy from the company. I'll be testing that soon. It's a commercial-UNIX specific one.

The other is "mtm" or Micro Terminal Multiplexer, which will probably need some work since it assumes GCC and I see GCCisms:

The reason I'm looking to this is because we're stuck on a 12-year old port of GNU screen, even if you use GCC or RSE: 4.0.3 

tmux is not currently possible, as it really wants unicode and stuff that IRIX just doesn't have. 

mtm is only around 1,300 lines. It's not 100% ideal, but it may be easier to maintain. 

If anyone else has other suggestions we have passed over, all ears.
