Adder for the Psion Series 3mx. Do you find that upgrading to a Series 3mx has left you wanting that old comfortable S3a calculator? If so then fear not, here is the solution. Adder faithfully recreates that S3a feel, and gives you a calculator that has all the best features the S3a had and the S3mx doesn't. And the best bit is that it is free! And I know that sentences shouldn't start with and. Or stop with and, or start/stop with or. But I have so there! Simply copy adder.opa to LOC::M:\APP\ and adder.rsc to LOC::M:\OPD\ if you want any help, and get addering. Adder should run perfectly well in installed from A: or B:. It worked well enough when I tried it but if you encounter any problems then just e-mail me. Everything else you could possibly want to know is contained within the help datafile adder.rsc. Simply press Help when in the program. Enjoy! Andy B. PS. the usual guff concerning disclaimers applies, so please be aware that the use of this program is entirely at your own risk.
