The nice part was that I could use it with a pay phone. Ah,
nostalgia.

Heh, I still have one. Want it?

Which one? The pay phone or the AJ acoustic coupler modem? I'll

Methinks I will need to regretfully decline your generous offer. I
spent my first half century collecting such things and am now spending
my next half century getting rid of the junk.

BTW, I previously had one of these:

but gave it to a collector of telco gizmos about 10 years ago.
