The most common top slot device was a simple power connector box in combination with a mains adapter. It fits into the top slot, and had a standard DC socket. The Psion mains adapter supplies 175mA at 10V. The later versions of the connector box have a little LED to show when external power was being supplied.
The RS232 Link was a top slot device that allowed the organiser to communicate with other devices, such as a PC, using the RS232 communications standard. It consisted of a top slot box (including a power supply socket) from which a cable extended that had a DB-25 connector on the other end. It was renamed from RS232 Link to Comms Link after the Psion protocol was developed, allowing for easier transfer of files to and from a PC running Psion's CL software. It seems that first versions of the Comms Link had a blue sticker, but that was quickly changed to grey. When the LZ was introduced, the Comms Link software was updated to use the full screen, and a little LED was added to show when external power was being supplied.
Barcode readers were probably the most common Psion II devices used in the retail industry. The reader pens were not made by Psion but usually by Hewlett-Packard. Shown here are two standard HP barcode reader wands (in black and in grey), a pistol-shaped reader reader (MSH-510) by Optoelectronics of Japan, as well as a combined barcode reader and comms link.
Magnetic card readers were also mostly used in the retail industry.
The Psion Printer envelops the whole organiser (minus its keyboard cover). It prints on thermal paper, and could have a magnetic card reader built in. It has built-in rechargable batteries, a slot for further devices, a power supply socket, and a mains adaptor which was a bit more powerful than Psion's standard ones, supplying 600mA at 10.4V. The printer shown here has a logo of the Natwest bank on it where normally there would be a Psion logo, and it is also missing the Psion Printer II label sticker that normally goes just below the card reader slot.
This is a very rare pager device. It allowed the Psion to receive text messages through the Vodapage network.
When the Organiser deletes data from a datapak, it is merely marked as deleted so that the data is skipped, but it still takes up room on the pack. The EPROM chips in datapaks cannot be wiped clean electronically. Instead, the formatter was used to empty the packs, which it does by shining UV light onto the window in the EPROM chip for half an hour.
The previous version of the Datapak Formatter has the style and logo matching the Series 1 Organiser. It was however also used for the series II for some time before getting replaced by this more compact formatter. To see that previous version, visit the Series 1 gallery.
The Eraser 16 is bulk datapack formatter. As the name implies, it can format 16 datapacks simultaneously. It has a long UV tube running through the middle, and you can place 8 packs on either side of it.
This is the Mark III Datapak Copier. It allows a single datapak to
be copied to up to 8 blank packs simultaneously. It also has an RS232
socket to allow up to 8 packs to be read or written to from a PC.
This version is branded by Data Innovation Ltd., but there are also ones with normal Psion markings on the outside. It seems however that the internal electronics where made by Data Innovation, so it may be that they were the regular manufacturer for the Psion branded ones, too.
It has an XP organiser built in. This organiser is connected to the rest of the device through a ribbon connector to slot B, and also by a bundle of wires through the hole where the contrast wheel would normally be. That bundle relocates the constrast control to a wheel on the main panel, and also supplies the 9V power. The organiser has no battery connector in its battery compartment.
The organiser needs a datapak in slot C that contains copier software.
