Welcome to the free downloads page. Here you'll find the bits of software written for Psion (and other) machines that I thought other people might find useful. It's all free, all that I ask is that if you like what you find then let me know. E-mail or postcard would be great!
I've acquired a Nokia communicator, so expect to see some S80 versions
of the software below soon. You can start by downloading the alpha version of Adder
(it's not in beta testing yet since it's still a work in progress).
Series 3a/3c/3mx software
Adder Version 1.1.0
For those of you who remember the Series 3A calculator with fond memories I present Adder. It came about when I bought a Series 5 and found that I didn't like the calculator. I preferred the unfussy 'get-on-with-the-job' interface that I had on my S3a, and decided to re-invent it on the S5. When I upgraded my S3a to the S3mx I didn't like that calculator either, so now the S3 machines have a S3a type calculator too. It comes in zipped form with a set of installation instructions and full help.
Adder Version 1.2.0A
This is the latest version. It's a beta version, but I forgot to change the version from alpha before I put it here (alpha is the testing that I do). Hopefully it's free of errors. I've included it here just in case anybody would like to play with it. So long as you're happy to accept that it might have a few teething problems then feel free to use it, and give me some feedback if you find any problems.
This version is playing catch up with all of the changes that have been included in the S5/revo version, so it sees the addition of:-
- verbose results, e.g. you can opt for 1+2=3 to appear in the results list
- a fix of the known inaccuracy bug in OPL's EVAL statement, so no more silly little errors like those in 1.1.0's help under known bugs
- engineering notation added to results formats, e.g. 5.5437E+03 instead of 5543.7
- unsigned binary, octal and hex support and results formats, e.g. b1001 = o11 = x9
- hours, minutes and seconds support and results format, so all of you pilots can better keep your log of hours flying
It comes in zipped form with a set of installation instructions and full help.
Buggies Version 4.2.0F
Buggies was originally written to aid in the derivation of gear ratios for off-road model cars some 18 years ago. It has since been developed over many machines and has seen a version on each Psion machine that I've owned. This is the latest S3a/c/mx version, and the best. It allows you to compare the ratios of 2 cars with each other at the same time (piccy below), and will also allow you to determine which gear ratio to run if all you are interested in is mm/rev travel (piccy not below, but see revo picture below for an idea of what to expect). This version sees a calculator that will convert between real speed and motor RPM. It comes all zipped up with installation instructions, an example database of model cars and full help.
Note that this version stores it's settings in a way that is incompatible with previous versions. If you are installing over a previous version of buggies the car name and pinion/spur settings will not be recognised, so you'll need to choose a car before you can use each of the calculators. From the first use the settings will be remembered again.
Mekmaker Version 1.5.2
Anybody that has played the FASA game BattleTech and had to make tweaks and compromises to get their ideal 'mech configuration should appreciate this. It's a little rough and ready since it was never meant to be released, but works perfectly well. It is, at least, a lot better than mucking around with pencil, paper and rule books! It copes with nearly all the Inner Sphere and Clan 'mech rules that were in place in The Rules Of Warfare (third printing September 1995) and the BattleTech Tactical Handbook (corrected fourth printing). It comes in zip format with installation instructions and full help.
Series 5, 5mx, revo and revo plus software
All the software below is zipped since I haven't got around to finding out about SIS files yet (the Psion installation scripts). Apologies for any confusion caused, but it's not really that complicated. When you've unzipped the files just put the whole application folder in to the system\apps\ folder on your S5 or revo. Each zip comes with installation instructions anyway.
Anywhere the S5 is referred to below can also be read as applying to the S5mx as well. The software below will run on the S5, S5mx and in most cases on the revo and revo plus too.
Adder Version 1.9.0F - revo friendly software
This is the latest final version of Adder. The full list of features is presented below:-
- a list that stores the last 20 calculations entered and the corresponding result
- 10 memories (M0 to M9) with memory in, plus, minus and recall functions
- support for trig functions (in degrees or radians), powers and logs
- different font sizes can be used, and zoomed between
- cut, copy and paste calculations and results to/from other built in applications (word, sheet, data, jotter etc.)
- the list can contain verbose results (sum and result on one line for easy pasting to another application)
- an optional second toolbar containing the standard operators *, /, + and -
- user-definable shortcuts to access the operators (instead of pressing Fn + another key)
- results formatting includes general, hexadecimal (signed 32 bit), fixed, scientific, engineering, unsigned octal, hex and binary (53 bit) and time (hours:minutes:seconds) notations
- calculations can be performed on decimal, octal, hexadecimal and time values
Buggies Version 6.2.0F - S5/5mx, revo and revo plus
As it says above Buggies was originally written to aid in the derivation of gear ratios for off-road model cars some 18 years ago. It has since been developed over many machines and has seen a version on each Psion machine that I've owned. This is the latest EPOC version, and the best. It allows you to compare the ratios of 2 cars with each other at the same time (S5 and revo piccies below), and will also allow you to determine which gear ratio to run if all you are interested in is mm/rev travel (piccies also below). This version sees a calculator that will convert between real speed and motor RPM. It comes all zipped up with installation instructions, an example database of model cars and more help than you could shake a big pointy stick at.
The code will detect whether it is
being run on a Series 5 or on a revo and adjust its appearance as necessary.
The S5 and revo screens are displayed below.

Lapcount Version 1.0.0F - S5/5mx, revo and revo plus
A freeware lap counter for model car racing. If you can't afford an automatic system, and you've got a revo or Series 5 then this is for you. Using the keys 0 through 9 you can run a race from 1 to 15 minutes for 10 cars. All you need is this software and someone to press the keys. Features include:-
- minimum lap time configurable from 1 to 30 seconds,
- results can be saved to a disk and directory of your choice,
- individual laps times for each of the 10 cars can be viewed after the race,
- race time is presented on screen, and updated in real time,
- during the race each car's laps and time so far are displayed each time a key is pressed,
- after race duration split times are taken for each car,
- program stops counting laps when all cars have a finish time, or
- finish the race at any time using a configurable key (default is @),
- lapcount remembers the settings you've used between uses,
- results can be printed from within Word.
The code will detect whether it is being run on a Series 5 or on a revo and adjust its appearance as necessary.
The revo screens are displayed below, the S5 screens are the same only bigger.
Mechmaker Version 1.0.0 - S5 and 5mx only
See the S3 bumph above. If you've ever played BattleTech you know what this is going to do!
PS. It's very unlikely that the revo will get this, I think it will need too much work to be brought up to EPOC GUI standards - let me know what you think.
Aibotone Version 1.0.0F - S5/5mx, revo and revo plus
This program replicates the tones emitted by the standard ERS 110 and ERS 111 aibo sound controller. If you're like me, you've always got your trusty Psion machine with you, yet you always forget to take your aibo sound controller whenever you take your ERS110/111 for walkies.
The code will detect whether it is being run on a Series 5 or on a revo and adjust its appearance as necessary.
The revo screens are displayed below, the S5 screens are the same only bigger.
Nokia communicator (Series 80)
Note that you'll need the OPL runtime installed on your Series 80 device in order to use the software below. You can get the latest version of the runtime for your device from the opl-dev project.
Adder Version 1.0.0A
For those of you who remember the Series 3A calculator with fond memories (and for those of you that remember Adder for Psion machines with fond memories) I present Adder for your Series 80 device. Adder has quite a history, and appears to have gathered a few fans on the way. I was asked if it was available for Series 80 devices, such as the Nokia 9300 and 9500 communicator, at about the same time that I was looking to replace my Samsung T100 with a Nokia phone (I much preferred the Nokia 7110 I had before the T100). I was aware of Symbian powered phones, but I wasn't aware that they had continued the work started by Psion and Symbian. It must have been kismet. So, Adder has made the jump to another platform.
This is very much a work in progress, hence the alpha suffix to the version number (meaning that it's pre-beta, still being worked on by me). It comes in zipped form, at the moment the zip just contains the application and apllication icon files so you'll need to create a folder called adder in the c:\system\apps\ folder on your device and copy the files there. When I've made more progress on the program I'll spend a little more time adding instructions and a help file to the zip.
In the main, Adder works very well at the moment. The vast majority of it's functionality is working, with just a few things to be tackled or tidied before it's first real release. It's had most of the replatforming work done already, such as removing the ER5 toolbars, removing pen support and adding the S80 AppFrame/CBA stuff (i.e. title bars, command button support and stuff)
Features:-
- a list that stores the last 20 calculations entered and the corresponding result
- 10 memories (M0 to M9) with memory in, plus, minus and recall functions
- support for trig functions (in degrees or radians), powers and logs
- different font sizes can be used, and zoomed between
- cut, copy and paste calculations and results to/from other built in applications (word, sheet, etc.)
- the list can contain verbose results (sum and result on one line for easy pasting to another application)
- user-definable shortcuts to access the operators (instead of pressing a key modifier, e.g. shift + another key)
- results formatting includes general, hexadecimal (signed 32 bit), fixed, scientific, engineering, unsigned octal, hex and binary (53 bit) and time (hours:minutes:seconds) notations
- calculations can be performed on decimal, octal, hexadecimal and time values
- title bar and status pane can be toggled on and off
Working:-
- zoom keys mapped to zoom function, zoom function removed from menu(added 19th July 06)
- status pane now displays the indicators (added 19th July 06)
- help key now invokes the in-built help, help function removed from menu (Adder specific help still outstanding) (added 19th July 06)
Being worked on:-
- help file format is probably totally different to ER5 devices
- hot key support might get added
- um, other stuff, I guess...
