What IBM keyboard is this?

And to which IBM terminal does it fit?







The 25 pin DSUB connector looks like the one used by IBM 3279 and 3278. The pins missing in the connector also fits with the 327x.
There are four jumpers on the decoder board which also fits well with 327x.

Anyone seen this keyboard and can confirm that it is for a 3279?

Replacement for the 3101 beamspring keyboard. Hence the odd D-sub connector.

But this one has a 25 pin DSUB. The 3101 seems to have a 15 pin DSUB.

Didn’t find any F type keyboard with the matching 25 pin connector.
