I've assembled some notes from old manuals and other sources
on the formats used for on-disk file systems through the
Additional notes, comments on style, and whatnot are welcome.
(It may be sensible to send anything in the last two categories
directly to me, rather than to the whole list.)
A few weeks ago, in a fit of nostalgia, I decided to gather together
a personal copy of the various Usenet source groups as still available
at places like gatekeeper.dec.com and ftp.uu.net. The result is
a collection of six newsgroups, net.sources, and then
I removed duplicates and fixed a few other archiving goofs as well.
The result is about 700M, uncompressed. It just fits on one CD. :-)
I have made a tarball available, it's about 145M, if anyone wants it.
Only one compression format; the .gz file is almost 180M.
I don't know of any non-8-bit Unix systems, but Multics, on the GE645 at
least, had a 36-bit word. See
