The main differences between the Psion Series 3a and the Psion Siena were the size of the screen (the Siena has a screen half the size of the S3a) and the Siena's IrDa capabilities.

MS-DOS ONLY
The emulator will ONLY run under a true DOS environment, and not a shell to DOS from within Windows. It is recommended that you SUBST the M, A and B drives. Instructions are given in the installation text file.

Beginners
In order to assist those who are not familiar with the installation of DOS software I have created a Zip Self-Extraction utility to run under 32-bit Windows. Simply double-click the installation file and copy the files to the C: drive, reboot to MS-DOS and type C:\SIENA at the DOS prompt to run. Simple!
