Software for Psion 3a/3c/3mx computers
(SIBO EPOC-16 operating
system)
Peter M. W. Navé programmed a few fine programs for the Psion 3a/3c/3mx series. They used to be on an English ftp site, but have disappeared from there since long. Now they have here a new home. Before download and use, please see the disclaimer.
Download the whole package (212 kB). Downloads: [off] (since 16.3.05).
It contains the following programs:
AccuTime
AccuTime operates up to nine simultaneous timers. Each call toggles the state of the timer between ON and OFF. The last 9 lines of the timer files are displayed by showing date and time of the start, the increments of elapsed time and the accumulated elapsed time. If the timer is stopped the last accumulated time is also shown as hours and hundredths of hours.
Calcon
A package with source codes of a date conversion program for the PSION series 3c.
CredCard
checks CredCard numbers.
DMMtr (recommended by U. Hornstein)
Using the PSION 3C as a data display and recorder for a VOLTCRAFT digital multimeter. Other instruments with a serial interface may be used after making the appropriate changes in the transfer protocol.
Connect the multimeter to the PSION 3c by means of the serial cable and an easy-to-make adapter. Instructions for making the adapter are contained as a HELP-window in the code. PLEASE NOTE: any electrical hook-up of the PSION with an external device are your own responsibility. I decline any liability whatsoever, as I have no control over the circumstances under which these manipulations are done.
The programme was thoroughly tested with the multimeter VOLTCRAFT M3850D.
The system VOLTCRAFT + PSION 3C + Software is characterised best as a small lightweight data recording system for slowly varying processes. Because of its low power consumption it is particularly suited for observations in the field of processes which are slow, have long (even years!) duration and for which electrically readable sensors are available.
This program has been ported to EPOC32. Various additional functions. Publishing in progress.
DumpFile for PSION 3c
DumpFile.opl is the source code of a file viewing (not editing) utility.
Fieldmill
The field mill is a parametric amplifier. Let the slots of the two horizontal disks of a field mill be aligned and connected by a resistor R. Because of the external field E the two plates exchange charges Q until their field cancels the external field between them: Q/C = E D where C is the capacitance of the device and D the plate separation. As one plate moves with respect to the other, the motor has to overcome the electrostatic attraction between the sectors. Simultaneously, C decreases and so do the charges because Q/C strives to cancel to the externally applied potential diference. Hence the attraction between the approaching sectors is less than the attraction between the separating sectors. The motor must supply net power to turn the disks. This power is consumed in the resistor R and any measuring device attached to it.
IconDraw
contains a utility for creating icons or other small images in
the PSION-S3 .PIC format.
IconDraw is really quite self-explaining
and needs no further comments. The source is laced with comments
which should make reading it easy. IconDraw can import pixel images.
See the folder Manipic for help with this task.
ManiPic

Soko-Ban
A solitaire board game. Full information is supplied in the form of help tableaus in the source code.
Sparrow
A solitaire game modelled after a game called Mah-Jongg which comes with the desktop KDE for the Linux operating system by S.u.S.E.
Stereographs
Two small programs to produce (auto)stereographs.
Tab2Vect
Tab2Vect converts a table with two columns into a graph which
can be imported into other applications, e.g. into WORD-97 by Microsoft.
The file with the table is a text file. It may contain data for
several curves. Each group of data starts with a head line which
is ignored by Tab2Vect. In each following line there are two numbers,
the first being an abscissa value, the second one the ordinate value.
All characters CHR(i) with i < 33 are legal separators; commas,
semicolons etc. are not. Both decimal points and decimal commas
are accepted.
The resulting graphs are either in the alphanumeric
CGM (Computer Graphics Metafile) format, extension .CGM; or in the
HPGL (Hewlett-Packard Graphics Language) format, extension .PLT;
or in Lotus 1-2-3 PIC. Only a few PC-based applications can read
the alphanumeric version of CGM, the more widespread CGM format
being the binary one which Tab2Vect cannot produce. The success
of importing any of the formats into a given application depends
mostly on the graphic filter being used. Such filters vary widely;
therefore there exists, unfortunately, no general assurance of success.
Those applications which convert the input graphic files into a
vector format, e.g. WORD which stores the graphic file in the Windows
Metafile Format, allow postprocessing the graphic in order to correct
or improve its appearance, see Tab2Vect.RTF for examples. Others,
like PaintShop Pro, store the graphic as a bitmap which can hardly
be altered, except for changes in size.
