I've managed to boot NS/OS - SPARC in a single user mode under the qemu-system-sparc emulator. Unfortunately it's not stable. And unfortunately it hangs and not crashes, so it's pretty hard to find out what's going wrong.
Is there a way to find out what keeps NS/OS busy if I only have the serial console? Are there any SPARC diagnostic utilities? I don't see any in the NeXTfiles/Software/Diagnostic_Utilities .
Is there a way to make OS/NS more verbose, than just '-v' boot option?
