The Soft Reset feature isn't too is useful(initialize hardware expansions), and there's but no used a lot, the [[PlayCity]] is the only hardware known to be (intentionally) expansion using that 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).
Moreover, there are probably various devices that do not directly use Port F8FFh, but that do react to the OUT because of incomplete port decoding. For example, the [[ACU Real Time Clock (DIY)]] decodes only A10,A4,A3 of its Port FBFFh, and so, it will also react to OUT [F8FFh],FFh.
