Emulators
Psion released a PC emulator,
S3AEMUL.EXE, advising that "the intended purpose
of S3AEMUL is as an unsupported tool for software
developers. The README.TXT file distributed
with the program states that "S3aEMUL will not run in a DOS
box in Windows" and "S3aEMUL will not run under Windows NT
or O/S 2" (this also applies to Windows XP, Windows 7,
etc.).
The emulator can be installed in a
virtual machine under, for example,
VMWare,
including the free (for personal use)
VMPlayer,
or the freeware
DOSBox
MS-DOS
emulation. The emulator was originally available for
download from Psion's own, now defunct, website, David
Kimberlin-Wyer pointed me to a copy of the emulator in
Gareth Saunders Psion website, on his
Psion emulators page. I have also made the download
available on this page.
