??? This was announced here not long ago:
http://minnie.tuhs.org/cgi-bin/utree.pl?file=SRI-NOSC
It's called 'NOSC' because that's where it came from, but it has the Illinois
NCP code in it.

hi,
im looking for Unix/Unix-like/Linux friendly hardware(desks,laps,phones,etc) free of proprietary software or compatible with free software(OS,BIOS firmware,etc) something that is easy to replace stock or something that cames with free software preinstalled and that i can replace them if i want to.
i've seen some lists that contain vendors that are Unix/Linux friendly and also the hardware endorsed by FSF which seem to be Lenovo thinkpads,etc the thing is it seems most of hardware require external flashing to replace BIOS,etc and makes the task harder..
my question are,
what are the bests Unix/Unix-like/Linux friendly hardware manufacturers?
which hardware is the best to make a computer 100% free (free BIOS and OS) and that is optimized and behave better under Unix/Unix-like/Linux based OS's?
Thank you.

Back when the dinosaurs were using card readers (and yes, I've used a card
reader on Unix; I think it was a desktop CDC model, and the driver would
handle two modes: strict 80-column i.e. one 12-bit column per 16-bit word
and you got 80 of 'em on a DMA channel, or ASCII NL-terminated after last
non-blank column, and no, I have no idea whether it handled EBCDIC or CDC
etc, but I digress as usual).
Where was I? Oh yes, sleeps...
Back when sleep(3) was sleep(2) (yes, Virginia, sleep() used to be a
system call, then it became alarm()/pause(), and now it seems to be
nanosleep(), and I'm wandering again), you never called sleep(1) because
its granularity was +/-1 second (and all the way up to +infinity,
actually, on a really busy machine), thus it could return right away, with
ensuing hilarity.
So, I'm curious:
When did sleep(2) become sleep(3)? Was it V7, or some BSD? Or Babbage
help me, SysVile?
When did the caveat about sleeping for 1 second become known? I don't
think that I ever saw it documented, but was one of those "lore" things
passed around at Unix conferences and the like.
And when did it start using nanosleep() instead of alarm()/pause()? I see
that my Penguin box has a bet both ways; it "may" use SIGALRM[a] (thus
"mixing calls to alarm(2) and sleep() is a bad idea" (well, I've used
both), and also refers to nanosleep().
[a]
Alpine's spell-checker suggested "SICKROOM" here; pretty close when
dealing with timed-out reads on a TTY connection[ii] :-)
[ii]
Have you tried this with Perl? You can't rely on EINTR[3], so you have to
use eval{} blocks instead, and it starts getting pretty fugly...
[3]
And here it suggested "ENTREE".

Also in AlphaServers we still have this TOY, the clock and the battery that is.

Before V7. The MIT system (~PWB1) says, on the man page for sleep (II), "As of
this writing the system call is still available although the C routine
implmeneting the function uses 'alarm' and 'pause' (II). It will be withdrawn
when convenient."
Probably left the system call there for compiled commands, etc which used it?

Very far back. CTSS had a mail utility.
If communication within one system is not
recognized as email, then the exchange that
opened in Boston in 1877 was not a
telephone system.
Doug
We lost Ray Tomlinson on this day in 2016; known as the inventor of email,
he sent the first message between two hosts on the ARPAnet (prior to that
the users had to be on the same host), and pioneered the use of the "@"
sign.
In the meantime, some tosser (his name is not important) is claiming that
he invented email first; I recall that APL\360 had a "mailbox" facility,
but it certainly didn't use "@".
