From the Gadgetmans shelves:
The Microwriter AgendA

Does this organiser look strange to you?
Of course it does with those 5 large unmarked keys.

What they are?
They are what is known as the 'Microwrite keyboard'. Pressing one or a combination of the keys gives you the alphabet or often used symbols.

But you probably want some details, right?

• RAM: 32KB
• ROM: 32KB
• Processor: ???
• Screen: 4 x 20 character LCD.
• Power:
  Built in: 5 x 1.2V large button type Ni-cad cells.
  External power: small circular plug with positive tip, and probably 6V or more.
• Connectors: A mysterious 12pin (2 x 6) connector at one side. Probably serial.

Here we see something strange on the mainboard. It looks almost like an expansion connector, but there's no sign of an opening in the case. Did they plan to make one and then later reject the idea?

Now, you probably want to know more about the 5 microwriter keys...
