You have missed the point. You don't NEED to do that to render things

Obviously. It was an easy point to miss given that you've only just got
around to actually making a point.

inoperable. I have decades of experience in this area, and one thing
that I learnt over 30 years ago is never to rely on interoperability
on those grounds alone. Here is one real life example where I have
seen such an issue - it wasn't a camera, and it wasn't any systems
currently available on a PC, but the principles are the same.

An awful lot of industry experience in interoperability and standards
has happened since the mid 1970s. Every camera manufacturer, with the
possible exception of Canon, is happy to benefit from that exception.

It is very unlikely THAT particular ``gotcha'' is present, but there
are a zillion similar ones that can be implemented without doing
anything non-standard. Until and unless I get confirmation from
someone trustworthy that Ricoh pictures can be read into (say) Linux
via a standard USB mount, I shall remain unconvinced (either way).

Apparently your decades of experience have left you with so many
suspicions that the only possible answer to your lack of question is for
you to get the CIQ and subject it to your testing regime.

I don't think you'll find anyone else here, let alone substandard me
(it's a couple of decades since anyone talked down to me as if I was a
juvenile so thanks for that) who can answer questions that you can't be
bothered asking.

Nick Maclaren.
Do you think you could apply some of your experience to implementing a
proper sig separator, please?
