Psion Organiser 1 Link-Up Communications
This in-depth information was published in the Canadian edition of 'Electronics Today' December 1984.

The Psion Organiser 1 LINK-UP interface which is fitted into one of the datapak slots. There is no top slot (D) on this Organiser!

The PSION ORGANISER 1 is the world’s first practical pocket computer - but its value doesn't end there.

With the LINK-UP industry standard RS-232 interface you can use your ORGANISER to communicate with other computers modems, printers and other peripherals.

Through the interface you can easily and quickly transmit a wide variety of information to the ORGANISER for storage in a datapak and later reference. Equally you can use the ORGANISER for data collection; information can he communicated later on to another computer system for storage and processing, or printed out at a hard copy.

The LINK-UP pack contains two components - the ribbon cable pack which plugs into a 'solid state drive', and a configuration module which plugs into the second drive of the ORGANISER to set the communication protocols, and which is then replaced by a datapak.

The parameters which can he set are extremely flexible and are selected by using the cursor keys to specify screen-prompted options including:

BAUD RATE:	150-9600
PARITY:	ODD, EVEN, MARK, SPACE, NONE
PROTOCOL:	NOTE, RTS/CTS, XON/XOFF

POPL - A POWERFUL AID TO PERSONAL POCKET COMPUTING

POPL - PSION ORGANISER Programming Language has been purpose designed for the Organiser, and enables you to write, store and run your own programs.

With POPL you can customise the PSION ORGANISER to exactly match your own requirements - whether you simply need to store basic and repetitive calculations for day to day application or need to create a sophisticated program for later use.

Contained within the Finance, Maths and Science packs, POPL is built around a set of simple commands such as IN, OUT and GOTO and has a versatile line Editor

POPL is a modular programming language, based on procedures, which can be combined and cross-referenced. Even the most complex and ambitious asks can he split down into a series of discrete and manageable elements. This approach is highly flexible and enables you to write complex programs easily and quickly.

CREATE PROGRAMS AS Individual AS YOUR PROBLEMS.

When any of the three program packs is plugged into the ORGANISER the MODE key provides options additional to those found in the base machine;

CAT: Lists all programs and procedures held in the program pack and datapak, if there is one plugged into the other 'Solid-state drive'.
RUN: Either a ready written program or one of your own stoned in a datapak.
PROG: Programming language.
COPY: Transfer information from one datapak to another.

When the Programming Language option is selected a further range of facilities specific to POPL are available.

EDIT: For writing and editing procedures.
INSRT: Inserts a program line.
QUIT: Discards your current procedure.
EXIT: Takes you out of PROG and carries the procedure into RUN.
SAVE: Copies an edited procedure into datapak for permanent retention and access.
ERASE: Erases a procedure from a datapak.

The comprehensive manual included with each program pack contains an extensive description of POPL and advice on its use.

Sections include:

Variables: INput, OUTput and Assignment.
GOTO, Branching and Labels.
Conditions: IF, AND, OR and NOT.
Looping and Iteration.
Globals and Arrays, STORE and RECALL.
Calling procedures. Parameters and Error messages.
