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.

Well I'll be darned! I read those post wondering what the diference was
between a Z90 and a Zenith Z89 (Which is what I thought is what I had) just
to finally discover that I don't have a Z89 at all. Better change that entry
in the web site.
Now I'm going to have to check all my machines and make sure I have all the
model numbers right :) .

True- although IIRC Busicom didn't actually use the 4004 as things worked
out.
There's a nice webpage devoted to the 4004 at:

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.

A talk on the SAGE System (1956-63) will be given at Moffett Field
on Tuesday evening May 19, 5:30-7 PM. SAGE was Semi-Automatic Ground
Environment, embodied as 22 monster computers (250 tons) each with
49,000 vacuum tubes consuming 3 megawatts of power. Parts of the
last SAGE system, decommissioned in 1982, will be behind the speakers.

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.

WHen trying to boot MS0:, from INIT 8.0-07, it halts at 20.
I boot 8.0 off the DU0:, say BO MS0:, the tape shuffles back and forth awhile,
and it stops at 20. What's that mean?
