It doesn't boot from any kind of disks, as near as I can tell -- just
auto-mounts them and hooks them into the RAM-resident filesystem. And
it doesn't buffer writes, so it's safe to dismount stiffies with the
eject button.
And having looked at the HP-UX 5.x manuals, "entire HP-UX system"
means "that subset supported on the IPC". It's pretty cut-down but
usable in a single-user stand-alone non-networked (not even UUCP) PC
sort of way.

A handy way around that is to use intersvr and interlnk provided with dos
6.x. Those combined with a laplink serial or parallel cable can allow you
to annex another systems drives for copies or installs. Using the
parallel cable is faster. It's documented in the MSdos useres guide.
I currently have a headless 386sx/25 with a few small hard disks, and two
non 3.5" floppies and a CDrom that via parallel cable and the interlnk
software serves and a sort of portable disk/cdrom/floppy to all my dos
boxen. It's real handy for systems that only have a floppy or tiny hard
disk. It saves having to have a network or anything more than a bootable
disk with the programs on it (they are small!). Once running all of the
disks on the server end are available as if they were connected locally.

Not exactly, it has a built-in floppy drive that you can boot from, or
you can use an external drive on the HP-IB. >BUT< they also had an
optional ROM that contained an entire HP-UX system. HP called it a
software engineering ROM. From what i've been told they're extremely rare.

I just picked up my third IPC. One of mine has the Technical Basic Rom,
one has the HP-UX ROM but the last one has both! :-)

Not necessarily, if it's done "right". Sun sparcstations and SGI
workstations come with the O/S on bootable CD, and re-installing doesn't
imply deleting all the other stuff that was added since the first factory
install. The O/S and support software/datafiles can be added/replaced in
modular fashion.

I kinda have to agree. My laptop has had a dead floppy drive for some time
now; probably over 2 years. The only time I really miss it is a) when I
want to move data/pgms to a machine/person not "connected" or b) when I
want to install (floppy-only) software.
The first is handled by the net, the second by getting software on CD (or
swapping my HD into an identical machine with a good floppy.)
Nowadays, data and programs are both so big as to make floppies unusuable.
(Can you imagine backing up 1GB to floppy? 8^)

Some years ago, when I was secondary school (grade|high school), someone
donated two calculators which sat on a side table in the school computer
room. One was a nice but not that rare wind-the-handle Facit. The
other was more modern and electronic.
The electronic one was interesting mainly for its display. It was
fluorescent (greenish digits sealed in a long glass tube), but not
7-segment. Instead, there were (I think) nine segments, all of strange
curly shapes, which made up digits much easier to read than the angular,
blocky, 7-segment types. But I can no longer remember how these were
arranged, nor even any details like the manufacturer of the calculator.
Does anyone know of machines with such displays?
At what date were they made?
Did anyone ever do an LCD version of these, and if not, why not?
And finally, what exactly were the segments and how did they fit
together? I've tried to reconstruct the arrangement, but try as I
might, I can't do it in fewer than twelve segments.

AmproLB a complete z80, 64k, 2serial, printer port and SCSI on a board
the size of a 5.25" floppy. I have one.
I also have a SB180 that is faster with 4x the ram on a card half the
size.
Neither stepped around the problem by putting all of the base software on
rom. The EPSON PX-8 did. I also did it for a s100 system years before
that. With EPROMS, EEProms and Flash ram as dense as they are a 1.44mb
floppy seems a lot of work.
