Datadisc background

Who are the Datadisc Ptthors?

John Crellin, David Crellin and Rob Dickinson. The very first version back in the 80's did not involve Rob (who was writing his own software which eventually became part of Datadisc) but essentially we have been the sole authors and suppliers of Datadisc for all of its history.

We are scientists whose principal aim has always been to promote data-logging in schools.

For a long time Datadisc was supplied exclusively through Philip Harris Ltd but that is no longer the case and Datadisc is now available directly from our company - ScienceScope.

All technical support for Datadisc is done by ourselves. In fact in time-honoured fashion we give credit to those who have helped significantly with Datadisc's development but, naturally, take full responsibility for its deficiencies and work hard to iron these out as they emerge.

Acknowledgments - as in the program itself.
Thanks to: Alison Bilsborough, Robert Crellin, Patrick Crellin, Maurice Elwell, Phil Godding, Steven Johnson, 'Numerical Recipes' by Press, Teukolsky, Vetterling and Flannery, Dick Orton, Dee Wood, Steven Wood and many others. Datadisc 32 has developed from DataStore for the BBC Micro over about 20 years.

We are aware that support queries may not have been handled as well as we would wish in recent years but now that direct support via this site and from ScienceScope is available we trust this situation is rectified.

Our promise

We are committed to support, and keep supporting, all Datadisc (for Windows) compatible hardware that has been made available up to the present time. (A very few items of hardware that were never supported by Datadisc for Windows but were by previous versions for the BBC computer etc are not supported.)

This includes the "Universal Interface and the sensors for it that were launched in 1990. Indeed we are working to ensure, as far as possible, that the very latest sensors from ScienceScope will work satisfactorily with the Universal Interface and DL Plus.

We may not be able to support hardware from other sources that may emerge in the future - for reasons beyond our control. Our endeavour will always be to deliver such support if possible.

We will also do whatever we can to ensure Datadisc will run on your school's computers. This goes far beyond industry norms as we know that Windows 95, for instance, must still must be supported. (Click here for information about a current Windows 95 / 98 issue.)

Networks cause particular nightmares - for us as well as (some of) you and our latest tools to deal with the problems these can throw up are quite sophisticated. Don't let anyone tell you there is a "standard school network" though - our support department will be able to talk your IT department through any problems though we are sure. (More on networks.)
Please note that the full-licence version of Datadisc is required for network installation - not an Explore or GraphPad only licence.

Ag / Au - confusing ?

We hope not. We think all software developers struggle with names as it is necessary to distinguish a significantly better-featured version.

Ag was so named to flag a significant improvement from Datadisc 32 and now likewise, the introduction of "derived sensors" - effectively up to doubling your range of sensors by recording other measurement directly - warranted a new designation.

We never (well very nearly almost*) reduce the features however. You should find that those facilities you appreciated in a previous version will still be available in future versions. Sometimes we need to re-arrange the menus a bit but the trusted feature should still be there round about where it always was !

A very good example is provided by the new derived sensor feature. this can be used during or after a recording and practically replaces the Calculate feature on the Data menu (many users found this rather tricky to use anyway). But the Calculate feature will remain on the program and it does have some capabilities not offered by sensor derivations.

* If you can convince us that one of the very few features that have been removed over the years should be re-instated (and basically if you use it we will !) then there is a small prize available. Just identifying these few is hard enough.
