Well, hearing an error on an audio CD might be difficult.
If cost is no object, you could have the data pressed to a mastered
CD, as opposed to burning a CD-R at home. The "real" aluminum
mastering process entails a "glass master" that might last longer
than the aluminum foil version. Are there any CD mastering plants
that give you an option of true gold foil, to avoid oxidation?

Take a look at the specification for how CDs are formatted. You may be
suprised to find out that a good chunck (more than just a few percent) is
dedicated to error correction! That is why you do not hear all of the
scratches in poorly handled CDs.

New subject: Looking for pointers to old Control Data software
I've just (mostly) finished an emulator for a Control Data lower 3000
(CDC-3300 and CDC-3500) system (circa 1966) and am using it to play with
an old operating system developed at Oregon State University in the late
60's and early 70's. Mostly it seems to run ok, so I'm looking to expand
my test sphere.
Does anyone on this list have pointers to old Control Data software,
specifically 7 track tapes (yes I can read these) and possibly
documentation (though I do have many of the old user manuals.)
Specifcally I'm looking for the following operating system:
MASTER Control Data multiprogramming "real time" operating system.
Support limited timesharing with users submitting "jobs" from
terminals.
MSOS A "mass storage" simple OS (more like CP/M except spool printing)
SCOPE A "tape based" system even simpler than MSOS
Any Diagnostic tapes would be helpful as well.
I'd be happy to copy and return (and in a newer media format) any such
items.
I've tried contacting the lastest version of CDC and they offer no help
whatsoever. Even refused to allow me to release copies of any of their
old manuals "for liability reasons." (don't get me started!)
Thanks,
Gary

OOOhh, nice ;-) What's it written in?

Unfortunately can't help you there.

That makes me sooo mad....

Does anyone know a friendly lawyer? Is there any form of legal wording
that can be used so that the company can't _possibly_ be held liable for
anything? If not, then there needs to be ;-)
Haven't they already used that in the shrink-wrap license?

That makes me sooo mad.... Of course I'm the sort of person who doesn't
drag people into court for
no good reason. I am quite happy to accept the normal English meaning of
'no support', 'sold as seen', 'parts or repair only', etc. I just
wish
the rest of the world would do the same.

I recently picked up a large disk platter labelled "CDC Model 848-8"
in a blue case. How many megs is this?
