Information on the Psion Organiser II series is available via anonymous
ftp to csd4.csd.uwm.edu:/pub/Psion.  The Psion archive will eventually
be moved to another site, a README pointing to the new site will be
remain at csd4.  Note that this archive consists almost entirely of
Organiser II files, there are very few files on any other Psion
machines.

The only way I know of to get information in and out of an Organiser is
through a device plugged into the top port (like the CommsLink serial
adapter), a storage device in a side port, or through the
keyboard/display.  The ports are parallel bus interfaces.

Here is /pub/Psion/Doc/specs for your convenience:

Dimensions:	5.6" L x 3.1" W x 1.1" D
		(142mm L x 78mm W x 29mm D)
		supplied with unique Serial Number

Weight:		8.8 oz (210g) without battery

Display:	2 line X 16 character, dot matrix LCD	[Model CM and XP]
				or
		2 Line x 20 character, dot matrix LCD	[Model LZ, LZ64]

		8 User Definable Characters

[From looking at a Comms Link I think it's like this:
   Front (keyboard/display)
		|
 _______________V____________
|                            |
|          +--------+ 1      |

|          |oooooooo|        |
\       16 +--------+        /
 \__________________________/

If pins 14 and 9 are connected (AC grounded) then the machine turns on. ]
