Otherwise know as Accutron Watches. Very fine and accurate.

Before that (mt Cessna still has one) there were clocks that used
A solenoid and contact to wind a mainspring for the usual wound
clock style balance wheel and escapement.

I have a copy scanned, I'll see about getting it on line
under http://bitsavers.org/pdf/cipher
Has anyone started to rebuild the boot disk/software archives similar to what
Don Maslin was doing? I see bits and pieces spread around the web but nothing
all inclusive such as what Don had. It would be great to see it all in one place
and mirrored in the same way as bitsavers.
I did find a list of the disks that Don had online (I think at Gaby). To the
best of my knowledge, that was the only online compilation of what was contained
in his collection.
I will forward your message to the Classic Computer Collector
mailing list. Perhaps someone there can help.

I don't think I'd call it a wall clock, but I have a clock like that
in the computer room.
It is octagonal and painted pink, so not my favourite, but I used to
use it to keep
an eye on the time so I could top up the diesel in the 3 Phase
generator which
used to run the mainframe.
I also have a clockwork car clock which gets wound by the movement of
the car.
That's way off topic though.
I wonder which was the first computer with a real time clock, what
year and how
it was implemented. I imagine it was invented primarily for charging
for computer
time. I think the first machine I programmed, the IBM 7094 had one
because if
your job ran over its limit time (30 seconds IIRC), the job was
aborted. Unless that
was the operator looking at his wrist watch!

I looked through FAST05 and found a few CMU
papers but nothing that looked like that. If/when
you find the link I'm very interested. My anecdotal
experience is based entirely on a hatred of
unnecessary technology especially RAID controller
failures (there must be a curse: the controller
barfs or loses its config more often than drives
fail!)
Interesting side point: in several case I've
been able to find files (tape images that I made
a decade or two ago) that I had misplaced (not
a drive crash but simply losing them in the shuffle)
by Googling for them and finding a copy of my
tape image, in a directory name that I had made
up twenty years ago, elsewhere on the web!
I was astounded!
Tim.
Anyone happen to have a source to a photo of the NeXT CDROM drive? Google's
being spectacularly unhelpful (one of those times where it'd be really handy
to be able to do a case-sensitive search :)
I'm interested to know whether the case styling was done in-house (and so is
in keeping with the rest of the product line) or whether it was just an
off-the-shelf unit.
