Music documentation

[Sgeo]

I would like to see some documentation on how to use the music disk.

I got as far as setting Alto I and turning on the DAC. https://bitsavers.org/pdf/xerox/smalltalk/music-help-1976.pdf implies that I should be able to type, for example, @hh@. That runs RAMLOAD (which I think installs microcode), but then the executive seems to restart. I have to then put in resume hh.sv2 to start Smalltalk. I was able to figure out to use down arrow for Smalltalk Do-it (!).

Other music doesn't work, and I wasn't able to figure out the filin stuff (possibly my unfamiliarity with Smalltalk-72)
