A PA6 can be made to work with discrete IO with an additional board but that is not what you have on a DMC. There is no way to reuse one of those FX or PY boards that I know of.
P86 is for TK controllers only like ICON, not for pre-thyssen/tk systems (i.e Miami Elevator, Lagerquist, Dover, etc), such as CEC Swift, DMC, LMH/T, Composite, etc.
