Subj: ACOUSTIC COUPLER

Hi all. I bought an aucostic coupler for an early DOS box (Hyperion) at the
Dayton Hamvention for a whopping $1.95. It consists of the two cups and a cable
terminated with a standard RJ11 jack. Red/green go to the speaker and
yellow/black go to the microphone. I want to use it with my M100 while on trips
(tired of dismantling phones and fighting with fancy non-standard digital PBX
phone plugs). Can anyone help me to interface this thing? I currently do not
have a hardware tech ref. I am trained in electronics, so I have no problem
building an interface circuit if necessary. Any help will be greatly
appreciated. Note: I have already tried to just plug it into the M100
direct-connect cable. No go.
