This is exactly my point of view. For example, I feel that Symmetricom 
was much "open" in terms to share the tech. documentation and some 
Once, I was struggle to get response from Microsemi sending them direct 
requests about the product (SYNCPOINT PCIE-1000 card, p/n 089-00376-000 
Rev 3). And only fellow time-nuts make it happens that I am getting 
right person to talk. There was no public resources available on 
Microsemi WEB site. Long story short - I was happy to get the Linux 
drivers and software for that card. But I am still struggle for the the 
microcode update (I have some "beta" version). Of course the firmware 
could be different story and it is not for free. But at least it would 
be nice to have that confirmation.

Speaking about Vectron - its also not easy to get tech. docs for the old 
versions of OCXO.
