I found this Web address (URL) with some information on the Microwriter AgendA: http://w3.hiway.co.uk/boog/aghome.html If you have access to the Web, you might want to have a look, or write to Mr. Warner at the email address listed below. Here's what this page says: Microwriter AgendA home page Information is requested for a homepage for the Microwriter AgendA personal organiser based on the original chord keyboard Microwriting system designed by Cy Endfield and Chris Rainey. If you are an AgendA owner please email me [log in to unmask] (Len Warner) with brief details of model and date. The intention is to provide a focal point to keep the remaining machines in use as long as possible. o Microwriter info: history, hardware and software versions o WWW links to Microwriter and alternative keyboard information o Letters and articles: selective archive of this list and other sources o Repairs and accessories: stay on the road o Secondhand market: let's keep AgendAs in the hands of loving owners
