Aw crap. This is what I get for writing from work from memory- my
machine is the 3100SX, not the 3100/20. Similar-looking laptop with a
plasma screen, but 386-based instead of 286. The hard drive in it is a
JVC JDE3896V10-1; the only connector on it is the 44-pin one, marked ISA
I/F.
The little 44-pin laptop connector is indeed just IDE plus power; they
sell cheap little adapters on Ebay to hook up to standard. This isn't one
of those; it's a header with "rectangular" pin spacing- between pins in a
row it's the usual .100, but between rows it's less. It mates to a 3M
#50144 connector, which Digikey says has .075 row spacing. The only
obvious pin is a big ground trace on pin 26. Perhaps it has the same
pinout- IDE on the first 40 pins, power on the next two, and ground on the
last two.

I'd always thought that the 3100/20 used that
26-pin interface, but maybe
there's more than one version; I've got a 3100/40 which uses a normal IDE
interface.
I /think/ the original 3100/20 used a proprietary 26-pin interface and the
3100e/20 used something more like standard IDE. There definitely is more
than one version. I recall a 44-pin interface which was IDE plus power, but
not sure if that's what's in the 3100e. It should be fairly easy to check
with a VOM, though.
