Ensoniq EPS 16+ Keybed question

I have a EPS 16+ and the keybed is hardwired but not working 100%. Sometimes it stuck on test mode. Sometimes keybed calibration failes. Sometimes works for a while but keys are lagging and got stuck when used for some minutes.

Im thinking of redo the hardwiring some day.
I might also get my hands on a EPS (the older version) and my question is if the keybed is compatible so I can move it over to my 16+?
Is it?
