WindEmu is an attempt to emulate various Psion PDAs.
- Platform-independent core emulation library written in C/C++
- Qt5 front-end (currently quite barebones...)
- Very experimental
- Basic support for multiple devices
Psion 5mx (EPOC R5) features:
✅LCD: implemented ✅Keyboard: implemented ✅Touch panel: implemented ❌Audio: not implemented ❌Serial/UART support: stubbed out ❌ETNA (PCMCIA/CompactFlash): mostly stubbed out ✅RTC: implemented ❌RTC alarm: not implemented ❌Standby mode: not implemented
Oregon Scientific Osaris (EPOC R4) features:
✅LCD: implemented ✅Keyboard: implemented ✅Touch panel: implemented ❌Audio: not implemented ❌Serial/UART support: stubbed out ❌PCMCIA: mostly stubbed out ✅RTC: implemented (needs testing) ❌RTC alarm: not implemented ❌Standby mode: not implemented
- State is not saved (just like a real Psion :p)
- EPOC misbehaves massively with memory banks larger than 0x800000 (may be an OS design flaw? need to confirm)

Special thanks to PsiLinux/OpenPsion for providing an avenue to learn about the 5mx hardware definitions (registers, etc).
More information on the 5mx hardware is available in the NetBSD port: http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/arch/epoc32/?only_with_tag=MAIN
The EPOC C++ SDK is available here: https://web.archive.org/web/20071010101808/http://www.psionteklogix.com/teknet/pdk/netpad-pdk/epoc_downloads.htm
The ARM variant used in the 5mx is documented here: http://infocenter.arm.com/help/topic/com.arm.doc.ddi0033d/DDI0033D_710a_prelim_ds.pdf
The datasheet for the CL-PS7110 SoC used in the Series 5 (not the 5mx) is available here: https://www.igorkov.org/revo/datasheets/CL-PS7110.pdf - while not identical to Windermere, some components operate in similar fashion.
The datasheet for the CL-PS7111 SoC used in the Osaris is available here: https://www.digchip.com/datasheets/parts/datasheet/096/CL-PS7111-pdf.php
The datasheet for the CL-PS6700 PCMCIA controller used in the Osaris is available here: https://pdf1.alldatasheet.com/datasheet-pdf/view/104907/CIRRUS/CL-PS6700.html
