That's odd, microengine-run-to is supposed to return the current 
*micro-program-counter*, not NIL. Having to hit the key twice is normal, 
each stage of the loader likes to discard the first keystroke it receives.

Let's see... Menu, disk A, Diagnostic, disk C, partition B, cpu tests, 
selected test menu, dispatch test. That seems about right, except that I 
only use one disk image on which I patched the partition table to make the 
diagnostics available (a single-bit change). 

You might check the value of *micro-instruction-pointer*. If it happens to 
be 40, try (microengine-step) once and then use microengine-run-to again. I 
believe I mentioned in the README that this happens at some point during the 
usual startup process. 

If you don't feel like patching a disk image, you could try to rig 
nupi-nubus.lisp to handle multiple drives.

Hunh. My most recent archive purports to be from October 2003, as does 
everything in that directory. If you want to revive LMH, feel free. I'll be 
happy enough to move over there.
