Changes in the Truss48/49 library:

v4.2SR2

- now spanish version available for HP49

v4.2SR1

- fixed following bugs of HP49 ported version:
  + plots no longer upside down
  + clock properly suspended
  + edit of input now ok (thanks Angelo!)

v4.2

- Now also available as Truss49, thanks to Edwin Crdoba who ported it to the HP49.

v4.1 to v4.2

- Due to the way directories were traversed by the use of the built-in browser,
  possible faults (e.g. insufficient memory) during the time Truss48 was active
  (after using the BROWse command in the OPEN file browser) were attributed to
  the xHOME command. This could also leave some rubbish on the stack. This is
  fixed in version 4.2.
