Organiser II summary
====================

I decided to write a short sumary for my PSION Organiser II tryings. So
here it is.

1. Devices
----------

At the moment I do have these models:

* P* (16kB RAM, 2-line LCD): SW must be modified first!
* CM (8kB RAM, 2-line LCD): too limited to many software
* XP (16kB RAM, 2-line LCD): much better but still limited
* LZ (32kB RAM, 4-line LCD): had sound issues, now works OK
* LZ (32kB RAM, 4-line LCD): weared off but works OK

I often  used the XP  one because I do  have several software  pack for
2-line units  (it looks ugly on  4-line devices). Bu 16kB  of RAM often
runs out when  I co coding and so.  So I returned to the  LZ models for
coding and so.  They also have better build-in  software (the calendar,
the note-taking app).

Now I use the last device in the list above. I actually got it recently
(I thought that  my main LZ has  issues so I wanted to  replace it). It
has a lot of  scratches, some buttons lost their labels  and so. But it
works  perfectly. The  other LZ  (which is  in almost  perfect cosmetic
condition) I now  use much less. I  still have to convert  the P* model
(and industrial  one which is  designed to  boot from a  dedicated data
pack instead  of use the  standard OS) to a  normal one. The  it should
behave as a XP model.

It is  good to  remember that  all the  models differ  in the  LCD type
(2-line or 4-line one), RAM size and in build-in software only. The CPU
is always 0.9MHz one, the serial port  on the top is always present and
they have two data pack slots.

2. Batteries
------------

All Organisers use common brick-shaped  9V battery. These batteries are
easy to obtain but re-chargeables of  this type are much less common. I
have got two GP branded ones and two Philips ones. The charger for them
was also more expensive than an usual AA/AAA charger. One 9V battery is
placed in the  PSION 3a keyboard adapter  so I do have  3 batteries for
Organiser II devices. Thus  I keep 2 ready (one for  coding and one for
shopping during emergency state) and one battery in reserve.

3. Software
-----------

During the time I have got some software packaged, for example:

* the Travel Pack (basic dictionary, converter and so)
* the Spelling Checker
* the Spreadsheet (bot 2-line and 4-line version)
* some software for barcode reader, the card reader and the data logger

From these packages  I use only the Spreadsheet more  frequently. It is
relatively simple and sometimes it is not so easy to use it on a 4-line
screen (not mentioning the 2-line version). T don't use the Travel Pack
now (for obvious reasons). I have  a temperature sensor (and a humidity
one, I thing) for  the data logger but so far I  haven't enough time to
play with it.

4. Accessories
--------------

I have got during time:

* the barcode reader (I should write software for it)
* the magnetic card reader (got it only recently)
* the data logger fit a few sensors
* the PSION Printer (2 of them)
* the Comms Link (a serial cable for Organiser)
* the USB Comms Link (a moder conversion)

From these  I have  used just the  Comms Link. Now  I use  the original
CL.EXE (an original software for MS-DOS). It should be also possible to
transfer files with the XMODEM protocol  but I find this one easier (it
does some data conversion automatically), even  if I have had to run it
under the DOSbox. But it runs well even on the Linux of POWER (with the
DOSbox, of course). If you have the DOSbox on your SGI workstation then
I may inform you that it runs perfectly here, too.

The printer  is an  another story: I  got two on  the eBay  before many
years (I  was bidding in  two parallel auctions  and won both).  One of
them was dead, the  second one worked. Then I abandon  both of them for
long time  and renewed my attempt  to use the printer  only recently. I
you may read I have managed to  make it somewhat work. The printer is a
thermo-printer  (as it  is  used  in many  cashier  machines) and  uses
relatively narrow  paper format but it  is OK for print  of OPL program
listing  or addresses  or  similar  stuff. The  printer  is capable  of
printing of  80 characters in  line (but they  are tiny, of  course) so
some text can be also printed. The OPL has the LPRINT command for print
of text lines, by the way.

5. Data storage
---------------

The organiser uses  its RAM to store data and  programs (the A: drive).
It has also  a pair of slots for so-called  datapacks. They are similar
of the SSD drives of Series 3 devices (but they are not compatible with
them, of  course). They are  almost brick-shaped  and they came  in two
types: a RAM pack (in has a battery-backed RAM) and a flash one.

The RAM ones are easy to use:  they can be formatted, data ban be added
or  deleted so  they behave  as normal  PC-style hard  disks. But  they
require some  electricity all time (from  the device or from  their own
batteries). And they  are very fast - both reading  and writing of data
is almost  instant. The  flash ones  don't require  any energy  to keep
data. But the data  cannot be easily deleted - they  can only be added.
To free  space on such disk  it must be formatted.  But such formatting
has to be done  with a special ultra-violet lamp. It  cannot be done in
device. Many flash datapacks also require a lot of energy for writing a
reading (their use can shorten battery life considerably). And they are
much slower than the RAM ones (both for reading and writing).

There are  different sizes: the 16kB  are probably the most  common but
32, 64 and  128kB ones also exist. There are  modern creations of sizes
up to 256kB (I  have one but it does not work for  me - my devices have
issues with it).

I actually  use a  64kB RAM pack.  The other datapacks  I use  just for
permanent  storage of  data  (I have  put  a 16kB  "low  power" to  the
outdoors LZ to store some data - but programs and other stuff is stored
in the RAM of this device - so on the "A: drive").

6. Cases
--------

I  have  several  cases  for  them: a  plastic,  canvas-like  one;  the
RealLeather one with the handstrap (not one but both the black and gray
variants); a simple black thin leather one. And an industrial hardshell
case.

At home I  store the LZ in the  later leather one. It is  very thin and
comfortable to  use. The Real Leather  cases are very massive  and have
very interesting  but very impractical design  of top part of  the case
which makes the device hard to use when it is in the case. By the way -
the Organiser II has keyboard cover which can be detached if necessary.
The cases usually require that this cover must be inserted to them.

The industrial case is more interesting.  It covers the device from all
sides and it  is waterproof. But the  device can be used when  it is in
the case:  the screen  is visible  (but protected  by layer  of organic
glass), the  keys are accessible (the  case has its own  keyboard which
mechanically transfers  key presses  to the Organiser's  own keyboard).
The  only inaccessible  thing is  the  screen contrast  thing. And,  of
course, the serial port is covered and it is not accessible at all. The
case is a bit bulky and looks,  well, as an industrial computer. But it
is ideal  for shopping  these days:  the device  is well  protected and
after use  it can  be easily  and safely  cleaned and  disinfected (the
device is  in so  case can be  washed before it  is opened).  With such
thing  in hands  one  also looks  strange to  other  shoppers. So  they
usually go away and allow me to shop more easily...

7. Desktop software
-------------------
I actually use  just a few pieces: The Comms  Link software for MS-DOS,
the CL.EXE (in the DOSbox where the DOSbox works). And the IDE (with an
integrated Organiser  II emulator), the  ORG2.EXE (the DOSbox  is handy
here, too). The IDE runs on my PSION MC600 laptop natively, too.

More   stuff  exist,   of   course.  ne   can   find  a   Windows-based
synchronisation tool or and on-line  device emulator. And some data and
program conversion tools, too.

8. Use
------

I have two main uses for my Organisers:

1. Learning  the OPL (Organiser  Programming Language). I  have written
several short  programs for  my work (well,  I can do  it in  any other
language  on my  workstation but  I  have wanted  to have  them on  the
Organiser, too) and I'm going to  write some others. I'm thinking about
making of some  program which will use my barcode  reader (to scan ISBN
codes of my books and to process them, for example).

I must say  that programming on the Organiser II  is more pleasant than
programming on the Palms or Zauri. There are several reasons:

* the hardware keyboard (with big distances between keys). 
* simplicity of device. No GUI mess is needed to wrote usable program
* simplicity of language. I don't like some of its keywords, though.
* availability of clean and simple emulator

2. Shopping. There  is still state of emergency and  new COVID-19 cases
are still very common (it's constantly about 20 cases per day and it is
not improving) so cleaning of everything  is still very important. So a
washable shopping list device  is of good use. I used  the Palm (III or
T|W) for this task but they cannot be cleaned so easily so I decided to
keep them at home now.
