== Known Hardware ==
The Soft Reset feature is useful (initialize hardware expansions), but no used a lot, the [[PlayCity]] is and [[Nova]] are the only hardware expansion using intentionally this feature (though when reverse engineering things by only examining the software drivers one may easily miss its presence, since the OUT [F8FFh] is issued by the BIOS, not by the driver).
Aside the [[PlayCity]], the other known hardware that is (maybe unintentionally) using Port F8FFh is [[CPCISA by Yarek]].
