we had about the system. Until we got our
hands on a BBC Master and opened it up,
we didn't know what special hardware we
would have to emulate! We started with
just one original Domesday set-up and
had a difficult time getting it working to
see what the resource actually looked like.
Other than seeing it demonstrated on
Micro Live (BBC1) in the 1980s I'd never
actually seen it running before.
considerable amount of time was
spent tracking down documentation,
licence agreements and staff who worked
on Domesday in 198586 in order to
inform our preservation work. A key prob-
lem with the development was the emula-
tion of the co-processor.With little
its delivery. Apart from the fact that its
complexity made it a challenging test case
for our work, by successfully tackling
Domesday the CAMiLEON team felt we
could go a long way to convincing the
emulation sceptics that there was potential
in this technique.
Were there any particular stumbling
blocks when it came to capturing
the original data from the discs,
or in producing an emulation of the
roducing the emulation was not with-
out its difficulties.There were many
stumbling blocks, not least of which was
the lack of knowledge and documentation
problem for some time. Domesday con-
tains a wealth of data in a myriad of file
formats. But it is the user interface and the
software behind it that really add so much
value to the resource.You can do really
quite advanced things with it; overlaying
local statistics on maps for example in
effect pulling together and combining
information to provide more useful and
informative views.The role of integration
that the software performs demands full
preservation of the whole. From a histori-
cal perspective it would be virtually crimi-
nal not to find a way to preserve the user
interface. BBC Domesday was a massively
innovative and influential landmark in the
development of multimedia and came way
ahead of its time in almost every aspect of
Screenshots from CAMiLEON's emulation.
