This is now working nicely and I've put the SDK and instructions on github. Everything is provided, you only need to clone the repository and run the install script to get up and running. I've tested it under a fresh ubuntu install and it all goes as expected.

Perhaps you could spin up a shell script to automate it or even a HyperV/VMWare/KVM VM disk and host it somewhere to encourage people to try it out?

Wow, great work. On Linux, I've run Psion emulators (for Window) through WINE, and without complaint, but to have an actual SDK install ... that's very cool.

Are you working on any app/process in particular? (That would be for another thread, I imagine)

Thanks again,
Jake

Ive got a bluetooth module in my 5mx. It allows me to connect the psion to the internet via an android phone and also can act as an HID keyboard for the phone, which is quite cool because you can put the phone on the psion screen and use it as keyboard and phone stand.

I went for BT because the power consumption is tiny conpared to wifi, I worked out wifi would kill the batteries within a couple of hours even for something minimal like an ESP. Max power consumption for the module I'm using is 40ma and it is possible to turn it off completely. And since I always carry a phone anyway it makes sense to reuse its wifi/data connection.

So my next task is to write a GUI to configure the BT module from the psion and Id also like to turn the module off when the psion is off etc if I can. Will write more about this project elsewhere in any case.

Im still having some problems with the compiler and trying and changing things, but a docker image or something is a nice idea for distribution, thanks for the idea C:Amie, I dont think it would have occurred to me.

Whoa, where did you find a bluetooth-capable 5mx? I thought they were legend only, like the bluetooth Mako.

I added the BT module, so this is a software and hardware project.

Although I do also have two of the BT revo pluses/makos (aka conans).

It's connected to the serial port (internally), although I did not disconnect the built in serial so its still possible to use it if the BT is turned off.

Amazing. Well, well done. I've always wanted a bluetooth Mako. I can't believe that you tracked down two of them. What's their battery condition?

They are different models, one looks more or less like a revo, and says revo on the case, but has a bulge on the lid where the BT module lives. The battery doesnt work on that one. Years later I was able to get a later prototype, a black one with conan branding and newer software, from an ex psion employee, and the battery works on that one. Both have hand written labels with serial number/software version on them. I have various other psion prototypes as well, perhaps I should make a post a thread with photos if it would be of interest?

If you have time, that would be great. I've always heard about these prototypes, but never seen up-close pix. You, by chance, never did the Revo backlight mod, did you? Or seen it?

I've never heard of a backlight mod for the revo, has it ever been done?

There was a rumour that on some versions of the revo ROM if you pressed fn+spacebar when the battery was low it would show a "battery too low for backlight" message, as the 5/5mx do. The rumour further went that there was unpopulated space for a backlight inverter on the revo motherboard. I've upgraded the RAM on a revo and I haven't seen any evidence for this. I think perhaps there was just a hangover in the ROM from the 5mx, but I've not even seen the message....

Having said that, if the revo does toggle the backlight GPIO when you press fn+space it would be possible to retrofit one if you could find space for an inverter board. EL backlights can be cut to size with scissors

To be honest, I used a revo as my main driver for a while and although I loved the size of it, I lost my data a few times and the keyboard is just really sub par compared to the 5mx. If they could have got a proper keyboard with decent travel into that footprint, and a micro SD slot, it would have been epic.

The conan does have a backlight (a blue one)!

My other prototypes are a psion 5 with transparent case, a bright green prototype 5mx (a lime), and Roger Nolan's prototype 5mx (which is bright yellow - a banana). I also have developer motherboards for the 7/netbook/netbook pro. I have other rare machines too; an original organiser with all accessories and most software, the acorn clones, ericsson MC218, MC400, wood effect 3a... I think that's it off the top of my head. I am missing some things like a linecker 5mx, some of the 3a special editions, transparent organiser 2, MC200, MC400, and perhaps the rarest of all, the white psion netbook pro LX (linux version). I've been collecting for 25+ years and to be honest it's gotten a little out of hand... I've had to stop myself collecting more for a while now !

Wow, the Conan had a backlight? Too much. Never let go of that one

Yeah, there was a Korean gentleman in the early 2000's who did the Revo backlight mod. His teardown was intense and he would do it for others for $50usd plus parts. Which is quite reasonable if you think about it.

His name might've been Ruey Loon, or maybe Ruey Loon was just famous for his detailed teardown.

What a collection you have. I hadn't heard of the Psion Netbook pro LX with Linux. Can that do security past WEP?

Oh I know the name Ruey Loon but cant place it! Great info, thanks!

The netbook pro supports a pretty recent linux, 3.x or 4.x I think, so it can do anything. The lx versions are the same as CE ones but double the RAM, and at least one came in a white case. But they never made it past prototyping, and I've only seen one picture of one, from a collector in Russia.

I found the revo backlight page and realised I have seen it before. But I do not know if it is the same person who offered it as a service previously. http://web.archive.org/web/20030511050720/http://www.kpsiug.net/plu...

I also found another page where someone built an LED backlight for a revo, and discovered that the revo really does toggle the backlight IO pin when you press FN+space. http://igorkov.org/psion-led

It should be possible to combine those two approaches to have an EL backlight that is toggled using FN+space, which would be quite cool!

I have got the SDK working really nicely now and have tidied it up too. I will upload it somewhere and post an update soon.
