Dear Editor,

The contents of the magazine seem quite well balanced – there must be something in each issue of interest to every Nascom user. I would like to see some explanation of essential parts of programmes, i.e. brief notes on those parts of software on which the operation depends. For example, a note on how the highres graph plotting software works would have been interesting. I would be particularly interested in articles on fault finding techniques for or with the Nascom. If anyone knows of a cheap and reliable MODEM design then the details would be most welcome.

The Lincoln computer club now meets on the 1st and 3rd Wednesday of each month at the Hare and Hounds, 330, High Street, Lincoln, starting at 19.30. Further details from:
