The connector is the correct one. It has four jumpers that could be used
for setting one of the keyboard types using the KB ident lines.

I was doing field service on 3270 terminals among other things up until
1983 and I never saw a 3278 or 3279 with a keyboard like this, all the
ones I recall seeing where an earlier capacitive switch keyboard that is
sometimes referred to as the "Beam-spring" switch.? That said this ones
does seem to have all the right keys in the right place for a 3270
keyboard.? The replacement product for the 3279 was announced spring of
1984 so 3279 may have already been out of production when this keyboard
was made.

It looks a lot like the keyboard for a 3178 except that has a DA15
connector and there is a blue switch on the top to select between upper
and mixed case.

Yes, it indeed looks a 3178 kb. But as you said that one had a 15 pin dsub.
This 25 dsub actually has the missing pins in the righty places compared to
the 3279 so I am leaning towards that it in fact is a 3279 compatible
keyboard. Will probably trace the lines and compare those with the 3279 KB
connector to see if at least ident pins and power pins is in the right
places.
Then I will just go ahead and try to connect it to the 3279 and see what
happens when executing the keyboard test (test 2) of the 3279.

It appears to be from a 3101?

The 3101 has 15 pin DSUB while this has a 25 pin D-SUB. So, while very
similar to 3178 and 3101 keyboards in many aspects I do think it is
different. Maybe some kind of replacement keyboard for the big original
3278/3279 keyboard. Will trace the connections of the cable some day to
verify, though.
