On this site you will find links to my Photography, and information about my Psion utilities, including RPNcalc, which is a Reverse Polish Notation full-featured calculator for the Psion Revo, Series 5 and related machines.
If you've never seen RPNcalc and you use the built-in calculator a lot on your Psion, you should try RPNcalc - it could save you a lot of time.
Other small programs here include:
- Ascii which displays the ascii character codes in Decimal, Hexadecimal or Octal.
- RPNbaby which is a stripped-down, simplified, freeware version of RPNcalc.
All my Psion programs work on the Revo.
Thanks for visiting.
