Hi All -
This is somewhat off-topic (maybe way-off-topic, depending on how you feel
about Macs), but I've been trying to find some 30 pin, 8 or 16 meg simms
for my girlfriend's Quadra 700. Anyone know of a source?

Dreadlocks on white boys give me the willies.
I'm not too familiar with the older DEC VAX hardware, but I've ended up
with a MicroVAX 2000 and a few strange parts.
H3104 -- 1 38-pin centronics on one side, 8 MMJs on the other
(I'm guessing a terminal adapter of some sort)
EE730 -- 1 DB9 and 1 DB15 on one side, 3 MMJs on the other.
( I don't have a clue what this is)
BC16C -- a 25ft cable with a centronics on each end
( I'm guessing this connects the H3104 to the MV2k)
What are these things? The middle item seems most puzzling to me.

The EL-8 was Sharp's original portable calculator from 1971 (in Japan in
late 1970) and cost $345 back then (for your basic 4-function
calculator!) The display is listed in my reference book as a flourescent
-type tube display.
I don't believe it used the 4004 chip - relatively few calculators
actually did use the 4004.

Yes, we should have "levels" of experience. So that a Level 1 job could be
done with anyone that knows how to wield a screwdriver... (things such as
adding RAM, a hard drive, or add-in card.), while a Level 5 should only be
done with someone who's had lots of electronics experience. (Such as fixing
a broken PCB or motherboard, the hard way). We could have tutorials to get
a Level 1 to a Level 5, but it would still be their responsibility.

Actually, I always thought that it was who ever could pay them enough money
to become a "solution provider." Seriously, we should have the Levels as an
internal rating system. I haven't seen such a system, but has one like this
ever been used? (It's better to use a pre-existing system then to develop a
new one, especially if the old one does what you want.)

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

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.

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.
Philip.

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.

Well, I scored a Panasonic Senior Partner (IBM-compatible luggable) with a
20meg HD. No matter what the product, I always like what Panasonic
manufactures. The design and (physical) user interface of stuff they
make just works for me.
Anyway, this one came complete with Rogue, Nethack and Mahjong installed.
I just enjoyed a splendid game of Rogue which I haven't played in ages
(made it to Level 8, Warrior with about 2500 gold).
It also had some C code, some unix utils in C:\BIN and a file pertaining
to Apollo workstations. Seems this machine used to be owned by a Unix
hacker for sure.

If this new Mac has no removeable media, what happens when the hard
drive breaks? How do you re-install the OS? Off the net? Catch-22, OS
isn't running, no TCP/IP stack. Off the USB? OK, then the boot ROM
supports bootable media from the USB? I'm impressed, even PCs don't
support that. And the removeable media of choice for the USB is? No
wait, let me guess, a scanner...you load the OS by scanning in bar codes
which contain the OS binaries. That would be, oh, about 100K pages to
scan in? Or you just send the whole thing back to Apple, and if they
have spares, and they are still in business, they send you back a nice
new pre-installed disk, sans all the software and setup you had on it.
Then you restore off the net, but uh oh, all you have is a 28.8Kb
connection, and 400MB of backup.
Good plan, system administrators will love this machine. No doubt
corporate types will beat down Apple's door to buy it.

Yes, of course. I wouldn't begin a quest of begging until I was sure
the item existed. No Holy Grail searches for me. I think there are
several categories of "lost": 1) it's somewhere in the vaults but
we can't find it, 2) it's in the vaults but no I'm too busy to get it,
3) I can't get permission to get it out, 4) I've got it but I don't
want to give it to you, 5) I can't give it you, 6) We'd have to pay a
lawyer to say we can give it to you, etc. down through N) the company
says they don't have it but an engineer we found on the net managed
to save a copy.
I'm more concerned about saving what we can, and getting official
permission to do so, and being able to reproduce it in a more
accessible fashion than it exists now. I can't do anything about
things that don't exist.

And perhaps this can help the argument. If a company has completely
lost or disregarded an asset that we can point out that they rightfully
own, perhaps they'll be more friendly if we ask to take care of it
for them. Buy-outs and acquisitions tend to prune away less valuable
(but no less *interesting*) technologies. My Quest involves telling
Lockheed-Martin that they own the Terak. Wish me luck. :-)

In my understanding of accounting, this "tax" doesn't exist. I think
the previous writer doesn't understand why the bean counters want to
get rid of inventory. There are certainly exceptions that rile
the blood of small- and large-L libertarians, but in my experience
in US small business, you are only taxed once. A B.C. wants to
reduce inventory for other reasons - it's money tied up in junk
that's not selling, not gaining interest, and isn't growing in value.
When it comes time to dumpster it, it becomes a write-off loss and
its original cost is probably taken as a deduction of some kind,
which alone makes it valuable to the bottom line.
So, the original poster's notion is correct - the complications of
taxation tends to make companies dump old stuff. It's like property
tax - it forces people to find a way for the land to generate at
least that much cash, which discourages people from buying land and
simply preserving it as-is.

I dunno how efficient it would be, but perhaps interested parties could
volunteer to format and html-ize old databooks, etc. for companies. They
wouldn't have to do any effort (except provide the source documents) but
then they could post them on their web site and make them available to anyone.

Not Nixie tubes as they were exactly 12 "segments" 0-9 and a decimal point
on either side. Their color was neon orange from the gas use to fill
them. They were glow discharge rather than fluoresent typically bluish
green. VF diplays were also available in red, yellow, blue, green and
white or combinations. Both technologies are from the "magic eye" tubes
and neon lamps of 30years+ prior.
The biggest difference between nixie from a calculator standpoint was
nixies needed about a 60-80 volt swing to ignite/quench at low current
where VF displays were typically 10-30v.
I have a 40x2x(7x5) dot matrix character display bottle (VF) and several
7 segment claculator displays also VF in raw form. Nixies, my Yasu 355D
frequency counter uses them (purchased new in 1974!) still works.
