It's not the hardware,as such - xyin is not implemented in the PC/Windows
versions. It would not really work in Winsound, until it becomes fully responsive
to GUI messages during performance.
I have code for reading the mouse in DOS (courtesy the Microsoft Knowledge Base),
which could in principle be added to the commandline version; the disadvantage is
that I have never found any way to get more than character-level resolution -
worst case 25steps up, 40 steps across! (There must be a way, somewhere  -
fractint has hires mouse control for example, but they probably hack deep down
into the bios or something).  I don't know about RTCsound; maybe  the problems
are the same.
