	On a healthy and bare Amstrad CPC, &FF is the value you can usually read on the DATA bus in high impedance state. On a healthy and bare Amstrad Plus, this is usually &78. This property has been used to detect the Plus machines in several productions (and failed on several occasions as this is not a reliable technique) [https://www.grimware.org/doku.php/documentations/devices/io.devices#blind.test Source].

	Some CPC emulators use Port &~~amp;~~FEFE to provide a method to identify a specific CPC emulator. CPC programs could use this ID to detect an emulator and change some of their behaviour (e.g. changing graphic ~~effechts~~ which will not work on an emulator or using special emulator-specific features).
