It would be good as well to dump the Series III main instruction set ROMs, 
assuming they're socketed.  Bitsavers has a Series II microcode listing, 
and there are some notes available on the microcode changes from the II to 
the III, but there is no existing Series III listing.

I've written reverse-microassemblers for the HP 1000 M-Series and for the 
1000 E/F-Series microcode, which could be easily adapted to produce a 
listing from the 3000 Series III ROMs.
