  11. Hi.
  12.  
  13. Friends of mine (and myself included) use HP 28s and 48sx calculators
  14. and were wondering .. is it possible to write a low-level machine code
  15. patch to display the familiar "Memory lost" message (and beep) when the
  16. erasure keys are pressed without actually doing so?
  17.  
  18. Thanks!
  19.  
  20. Cheers,
  21. %Ben%
