Joe:
You've just described the power supply for one of our
Intel ICE's (one of the *really* old ones). The sides
a slightly sloped like a FLUKE PTI style case, right?
Almost certainly used with one of their (Old) emulator or
dev products.

Iggy,
You are in a rare and enviable position, if you really don't care
whether what you get is the original or a copy. To you, if I interpret what
you say correctly,
- A CD and Walkman is better than a night at the symphony (cheaper, can be
replayed at will).
- Safeway (a chain of grocery stores in the US) generic root beer is better
than A&W (cheaper, still floats ice cream)
- A Saturn (car) is better than a BMW M3. (cheaper, more dealers, still
gets up to the speed limit)
- A print of the Mona Lisa is as good as the original (and can be rolled up
and stuffed in a tube for transportation or mailing).
- This year's repro Mark-8 is as good as a 1970's one (and more reliable).
- Corner liquor-store champagne is as good as Dom Perignon (still bubbles, you
still get tipsy when you drink enough).
This is wonderful for you because you can afford all the ersatz
experiences a *lot* more easily than I could afford all the originals. It's
also slightly good for me, because it means you won't be competing with me
if I should ever have a chance to buy the Mona Lisa (or a BMW, ...).
I *know* there are differences between the originals and the
copies, in all of the cases I listed above. In three out of six, I am well
enough equipped to appreciate them, and I would *really* want to see/use
the original at least once, even if budgetary constraints forced me to live
with the copy long-term. (ie: go to the symphony and then buy the CD,
hoping it would help me remember some of what the symphony was like).
In the other three cases, I don't appreciate all of the
differences. But because they *are* copies, I *know* they are there, and if
I ever become better educated, I may regret owning a copy when I learn what
they are - or I may forever miss out on some subtle beauty of the original,
because I settled for a copy. Suppose I never drove a BMW - a Saturn always
got me where I was going. I could easily sneer at people who "wasted their
money on BMW's", out of ignorance. The fact that I really wouldn't be able
to tell the difference as I was learning to drive doesn't mean I'd never be
able to tell.
The same applies to research on the history of the creation of the
original. Maybe the PC board was laid out a certain way to facilitate test
during assembly, or because the designer knew his PC etching technique
wouldn't support two vias too close together. If Speedy Circuits can now
put 10 vias in the same space, and the "copy" is laid out to take advantage
of that, some history is lost, whether original 1970's parts are used or
not - and if I am researching the copy, I'll never notice it.
And I don't buy the argument that any copy will ever be the true
equal of the original - it may be pretty close, *in the characteristics
that the copiers care about*, but it won't be the same.
Finally, and this may be the point that you and Sellam are most at
odds about, there is a component of emotional state that is important to
any experience. If you are able to put yourself into the same emotional
state before and during viewing a copy of the Mona Lisa as you would be
viewing the actual Mona Lisa - good for you. It'll save you the price of
admission to the Louvre (or where-ever the Mona Lisa is).
I can't. I think, based on his arguments, Sellam can't (correct me
if I'm wrong here, Sellam). To us, the knowledge of what we are looking at
is a critical part of experiencing it. It's worth something (though it may
not be worth the cost of buying the thing, either), and it means we do not
regard people who value originalty (and pay a lot for the originals) as
"idiots" - we share some of their values. It doesn't mean we won't use
copies either. I've never seen the real Mona Lisa, but the copies I've seen
are good, and I've enjoyed them.
But I want to see the real one, someday.

Never expected this response to a bunch of magazines
Already have 4 - 5emails. Talking with people in order of emails received,
if they look at shipping and pass, I go on to next. But already have 5 so
thats pretty much it I guess someone in those 5 will be willing to pay
shipping.
Thanks

Another good fact to add to the Apple I vs. Sun analogy is the fact that
Apple is credited with pioneering the desktop/home/personal computer market
(mass market that is), while Sun didn't invent the workstation (though
they'd like you to think so). For what it's worth, Apollo invented the
workstation, though Sun was around fairly soon afterwards.. What irks me is
that I read an interview with some Sun guy about the Sun Blade and they
claimed they invented the workstation, which is untrue.. ugh. The Apple I
also, as was stated, had a very small production as well, and it was the
very first product of a company that is still around and very famous, though
I'll exclude any thoughts I might have about their hardware... Along those
lines, think what a PDP-1 would be worth, with a production of 50 or so, and
being A. DEC's first computer system, and B. the machine upon which Spacewar
was created.. It is irrelevant if you like or dislike DEC (or Apple), you
still can't deny they have made a lasting mark upon the computer industry,
unless you like to make yourself look at least somewhat clueless... Just
like Da Vinci's ideas, though not so much his paintings, have had a profound
influence on Western civilization...

Yes, that is a spec'ed item delay after index. The cheap fix, delay
index
about 95% of one revolution, fakes it into thinking it occured earlier.

Depends on the precomp needed. for single density it's fairly lax, for DD
that might require tweeking or not.

If you have the drawings, it may be easier. Many more parameters are
alterable that way.

It will do single and double 8", unless the board compromized and
used a half speed clock.

It's a setup and config issue.

I'll be there, barring any catastrophe.

The DN10000 is the bit-slice implementation of the RISC chip Apollo
designed.. Here's a note from a computer architecture site:
PRISM (3-wide LIW), 1988 - Barry Flahive, Rick Bahr, and John Yates
John Yates contributed the multi-issue idea. PRISM was a 3-wide machine --
in each successive clock tick, you could do a floating-point add, a
floating-point multiply, and an integer operation (typically a LOAD, for
instance of two floating point registers). Perfectly balanced for
single-precision Linpack or FFT.
DN10000 - the first (and last) model, 54 MIPS, 36 megaflops in 1989.
Paul Mageau and Andy Milia were chiefly responsible for the memory system.
Doug Voorhies, Olin Lathrop, and Dave Kirk were chiefly responsible for the
graphics system.
Therefore, the DN10000 is the bit-slice implementation of PRISM... A bunch
of the stuff in PRISM went into PA-RISC 1.1, I believe... The date for
PA-RISC 1.0 is 1987, don't know now of any machines besides one model of
3000 that use it...

Hi all from Montreal.
Big piles of Amiga mags. Donated from frequent collection contributor (ex
local DEC employee).
Mostly Amiga World 1989 - 1995. A few .info, Amigo Times, Transactor,
Amazing Amiga etc...All great shape.
Sorry no time to list issues here. Not even time to go through
them...Perhaps you are looking to complete some years or whatever. Ask for
issues, Ill get back to you quick, I check email often.
Free for just shipping
You can ask for one (cheap to ship) or some....or all of them ($$$ to
ship...)
Please hurry cause these will go in recycling bin in a few days.
This is not a trade - these are offered free....but you can always remember
me now or in the future....I collect mostly "home" micros 197x-198x 8 and 16
bits...some machines rare here in Montreal...and common in US...
Thanks
Claude
