It has battery
terminals on its inside end. Obviously the battery pack must fit
into the same space when the machine is on the move. There's some
other kind of connector on the end of the AC adapter, too, but I
don't know what that's for. Also, why is there an external 16VDC
connector if the battery slides into the case?
I suspect that the connector on the inside end of the AC adapter joins
with the external 16VDC connector via a cable, so that AC power can be
used with a battery installed in the unit, allowing recharge.
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
There are four
banks of RAM on little boards, kind of like SIMMs but
not. The board edges seem to be soldered to the motherboard. There
are four empty spaces for more of these things. 30 pins each. Or
is that what 30-pin SIMMs are supposed to look like? :)
Actually, it turns out these are SIPPs. Never had a machine with SIPPs
before. Didn't know what they were.
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
Yes, I am talking to myself.
I feel like I'm doing that a good majority of the time. :^)
