The Genlock card is in a shoebox but I can't remember which shoebox.  I
don't think there is any software with it but there is a CD with fitting
instructions and photographs.  It was advertised by Chris as a Genlock
card for video titling but it is the same as the "Domesday" one.

The article about the Domesday Project was in July 1985 edition of
A&B Computing.  I have put the images here:

If have also found that I already have some images of the same Master AIV
from E-Bay and here is one of the pictures showing the Genlock board:

Curiously it has the System ROM on the little carrier board and a video
output from the Genlock board fitted to the back of the casing.

Best wishes,



Ian

wow. Did you get any other stuff (docs, software) with it? That makes the 
total number of known people with one of those genlocks a whopping four :-)

Interesting - any idea which mag? I could scour the collection at Bletchley 
then and scan the article (I've done that with a few Domesday-related bits, 
but don't remember a pic of the top-loader)

If I'm getting my model numbers right though the VP405 is a top-loader, and I 
believe we have a stash of those at Bletchley - they're pretty basic compared 
to the later players. Would take me a while to trawl email archives to check 
who told me that the 405's served as the first dev systems...

Yep, that sounds a fair assumption - maybe they had trouble with overheating 
issues or signal quality with the genlock in the beeb...

cheers
