Bad luck. The CD's are lost (unreadable actually). Not surprising seeing as they
were old and had been tossed around so many times (sic).
Maybe the original request for Mach sources should be redirected to comp.os.mach
or to some of the original authors to see if they still keep something around.
It might be that even CMU keeps something.

I *think* I have.
Thank goodness yo mention this! I believe I have copies on CD-ROM dating back
from '94 or so. I'll dig them up. The problem is I believed I also had them on
the FTP server, but they aren't. I must have lost them on one disk crash or
another and didn't notice, so your question is great for I might part of the
original CDs and lose it.
'nuff said. I'll check this afternoon when I go back home and try to find
again
those old CDs (cross your fingers).

I remember a very old SONY cd-rom reader capable of reading very
damaged cd! It was the SONY CDU-33A, it has his
own controller, so was not an IDE or SCSI drive. But it can be
connected to an old soundcard like Spectrum or other similars,
having some cdrom interfaces.
sorry for my bad english :)

Is there
anybody on this list who knows a way of recovering flaky CDs?
Easiest first step is
try using different kinds of CD/CD-R/DVD-R drives.
I have found some 'unreadable' CDs could be read using a DVD drive.

It depends. If the content is not damaged then you can probably "wipe" them.
I mean, look at the printed side: if there are scratches there chances are
the data is damaged as well and you may be out of luck (depends on whether it
affects the catalog).
However, if the printed surface is not terribly damaged, and the problem is
that the mirror-looking side is scratched then your data may be healthy and
it is surface irregularity that distorts the laser. There are kits out there
that can wipe the surface and render it again smooth. I used one such kit
several years ago with good results. Casually, it's on the shelf in front
of my eyes now.. lemme see... It says
CURTIS disk restore. Radial scratch repair and cleaning system for
CD/DVD discs. www.curtis.com
According to the box it will not repair gauges, deep scratches, label-side
damaging or warping.
