I can't speak for all 386is - however mine has a breakout cable that
keyboard, mouse and video all ride on. It definitely does not have a
keyboard port on it (either the earlier DA15 or the later DIN).
On mine the upper-most peripheral slot (I don't know what the type of bus
it is, but I think it's custom to the 386i - there's actually another
slot above it that is for the processor/RAM) has a rather curious custom
connector that looks sort of like a 13W3 but isn't - it's something like a
20(?)W4, see picture here:
This requires a rather hefty and long break-out cable that goes from this
connector to a separate video and keyboard cable (I can't remember it's
specifics right now, but I'm pretty sure it's DIN). I have two of these
cables, actually, one that goes to BNCs/keyboard and one that goes to
13W3/keyboard, but the 13W3 cable never worked on any monitor I had, while
the one with the BNCs worked.
If yours matches this funky whatever-W4-connector let me know and I can
pull the cable out, take some pictures and use a continuity meter on it
and map its pin out.
Alas, my 386i stopped working some years ago and I never went back to it
to diagnose the fault - but it was fully functional at one point.
