- The address given for GetSerialNumber in the "Hitchhiker's Guide To GEOS" is obviously wrong: $4b38.

- According to the "Hitchhiker's Guide To GEOS" GetSerialNumber returns a string on Apple GEOS (in contrast to a number on CBM GEOS).
Given both facts and that the API is presumably not important at all it seems reasonable to just go without it on Apple GEOS.
