The HP50G entry points are more or less the same as that for the HP49 and HP49G+. The addresses themselves may be slightly different depending on what ROM version you have, but the list of entries can be found at hpcalc.org.
You may also want to download Debug4x (also available at hpcalc.org) which also has the complete list of entries.
