They outsourced support to India, and all traces to what happened to
the software have vanished.
So, in addition to many companies being reluctant to release rights to
IP, a lot of stuff is just lost without a trace.
Yup.
Parts of the DEC Networking group got sold to Cabletron and then bits
transitioned to Riverstone. Later VAX/PSI code made it as far as the US
engineering team (who by then were part of EDS iirc). I don't know
whether a copy of the DECnis code stayed with DEC - the copy with
Riverstone wouldn't have gone any further (there were big layoffs
involved so I doubt that anyone was checking that nothing vanished).
More or less the same will be true for the Riverstone code. Some of it
may have survived the fire sale a few years later but I suspect tracking
any of that down might be hard to impossible.
The code I wrote at BlueARC is still going at Hitachi Vantara but the
long-dead Si7500 code may no longer be on anyone's disks there. It was
preserved on a set of DVD-ROMs (as part of the regular backup regimen)
but the guy who handled that has left and there is probably little
incentive to make sure it hasn't slipped through the cracks.
At least in the open source world (where I now work) most things are in
a github repo. Admittedly those things do vanish every now and then but
at least you have the chance to grab something now if you think it will
be useful. Although given how interconnected things are these days,
building something in 2030 that last built on today's Ubuntu 19.10 (or
whatever) may require more effort than you think it is worth ... but at
least you'll have the source code.
