Does the #psion5 have a rom version that included the installer program so you can install SIS files direct from CF?
Mine lacks the installer - I can add it via psiwin and serial but it's a pain!
I know the roms are on a daughterboard - are they flash or mask roms?

Some #Psion news! #plptools, the open source suite of programs for transferring files to and from #EPOC16 and #EPOC32 devices, has some additional maintainers... including me!

A selection of Psion portable computers.

Did you write code for #Psion machines in the #80s or #90s?

This is a call for you to #opensource your code!

Our community is breathing new life into #EPOC16 & #EPOC32. New dev tools, apps, games, docs. Your old code will help!

OPL, C, C++, #assembly.

By the way, because I'm picky:

The OS was always called EPOC (actually "Epoc/Os"), never SIBO.
SIBO is the 16 bit hardware.
#EPOC16 and #EPOC32 are retronyms (but I like them).
EPOC16 and EPOC32 are completely different OSes with the same name.
EPOC32 evolved into #Symbian.
