INTRODUCTION:

This program doesn't work on S/G calculators.
The program shows the status of ports and the free memory
in each of them. It also shows the free system memory and
the PORT0 used memory.
For PORT1 and PORT2 it shows the kind of  card (32K or
128K) and the status of write protection (ROM, FREE RAM,
MERGED RAM and EMPTY).


FINAL REMARKS:

- When any of the cards is FREE RAM and it doesn't have
  anything inside, the program fails and the calculator hangs.
  Nothing else happens but it's quite annoying.

- The program has been developed on a HP48SX with the RPL48 v1.12b
  DEVELOPMENT PACKAGE, the DEBUGGER 1.0b and ED.
  It is completely written in Sys-RPL and it's 545 bytes long.
  It makes use of many "unsupported" entries. Use it at your own
  risk. It has been working for months on a HP48SX revision J and on 
  a HP48G revision R and nothing wrong has happened. However, remember 
  to backup your memory before using it.



ACKNOWLEDGEMENTS

I would like to thank the following persons:

- Detlef Mueller and Raymond Hellstern for RPL48
- Mika Heiskanen for DEBUGGER and ED
- Julián Garrido for helping with autoexec libraries that gave me the idea
  of making the program
- HP for HP48 and TOOLS


As I explained in the DISCLAIMERS part, this software is freeware,
but many hours (and days...) of programming and debugging have been
invested in developing this library. So, the author will be much more
than satisfied if someone tells him that he appreciates the library
and he uses it a lot. Author will also be glad to solve (or at least,
try to...) all the problems that you can find using TTT4D.
For this reason, you can contact me by:
