I have what sounds like a similiar adapter on my NEC Prospeed 286 LT.
There's a 2-prong DC connector on the rear body of the LT like the ones on
many portable radios and a regular AC socket on the slide out adapter.
When removed you can see another 2 prong AC socket on the rear side.
There's also a led on the main body labelled AC Power which remains lit
even when the LT is turned off. I had surmised that there was a battery
in the adapter but when I opened it up, some time ago, could see nothing
that looked like a battery. I'll have to look again. This still begs the
question of why the 2 AC sockets, unless they were used to charge the
damn thing since it won't work unless it's plugged in. Seems like an
awkward solution.

 The Pro-S. has 2 compartments, accessed externally labelled Memory and
Modem. I think the modem was proprietary guaged by the connectors. What
looks like a small power plug and a 20-pin socket.
The larger memory compartment has a connector that looks like a mini
centronics socket. Kingston used to have them but I found the price
prohibitive. Besides which the beast weighs about 20-25 pounds.
 I was lucky enough to get the set-up program and other info in their
archives thru the NEC BBS and a lengthy, expensive, long-distance
phone-call.

 I feel like I'm doing that a good majority of the time. :^)
