Do you think a ``Call for dusty Paper'' CfdP (TM) on the Usenet in groups
like comp.sys.mips or comp.sys.sgi.* might make sense?  I bet there are
still people out there, maybe former SGI employees in the meantime which
have helpful data around.

I'm currently doing some brain surgery on some OEM machine which identifies
itself as RS3230 and is running RISC/os 4.50 :-)

As I already wrote to Richard Masoner - it's not uncommon that people
write GPL software while being under NDA.  The company reviews the code
when it is finished and gives it's ok to publish it but the documentation
(whatever it consists of - paper, code, electronic files, drawings ...)
will stay undisclosed.  In many cases this is a way to keep both sides

Since you mentioned the various graphic subsystems above - do you think
the implementation of a ARC firmware text only based console might be
sensible?  I've got several requests for Linux from people who have a
XZ graphic which we don't support yet - and there is quite a number of
graphic options for SGI's out there so this might be somewhat helpful.
