Greetings. I understand that the BBC uses a proprietary part numbering
scheme when specifying components. It is also my understanding that
certain UK distributors/resellers use this part-numbering scheme in
order to make life easier for the BBC. My areas of interest are video
& audio cables & connectors. I have been unable to find any
information on the web on how to obtain the list of these part
numbers.
 In order for this question to be answered to my satisfaction it must
include the following: a link to an online database of BBC part
numbers or information on obtaining a physical document. Either of
these options must include information on video & audio cables &
connectors. Information containing the BBC's required specifications
for audio & video cables would also be helpful.
Happy hunting!
