I am wondering how useful a ROM listing is without scheamtics. Surely for
something like this you need to know how the firmware interacts with the
hardware (what the various I/O ports do, etc), and that means (at least
to me) scheamtics and documented ICs.

For which you don't get service data, presumably.
The transport (motors, laser pickup, etc) is probably the section most
likely to fail, and the section with the most alignment adjustments. I'd need
service data on that.
