While digging through one of my boxes of stuff for a part I found a
partial S100 Jade Double density disk controller kit unassembled. Of
course I remember why I had it, the person that gave it to me back in
'82 wasn't up for the assembly task, raided it for parts and gave
me the remains. At the time I wasn't interested in getting a 1793 based
controller going as I was getting 765As for free and all the assistance
>from it's designers I could use. Well guess what. I'm 98% of the way
through assembling it. Then I have to assemble the source code as there
are no disks but lots of listings in the manuals. It's z80 based in that
it has its own CPU as a bus slave. Should be interesting to get going.
Oh, all the missing parts are from my collection and a few are date coded
before the board! It was all I had of some parts.

Right. Not too many people are going to agree on this. There's
probably a few people out there who think the Atari Portfolio is a
classic and I think it's under 10 years old. The IBM PC/AT is 13
years old now but I have difficulty thinking of it as a classic and I
really couldn't care less.
But the 10 year rule is simple and not without precedent (it's roughly
the way other things are judged "antique" -- if I remember correctly
the "magic number" is 100 years for furniture and housewares and 20
years for automobiles). That's why we have it, we know it's not
perfect but it does provide a clear cutoff.

Does it? The problem is that inside 10 years it's very difficult to
judge historical significance.
And just because it's older than 10 years doesn't make finding the
historical significance any easier. I'm hard pressed to think of what
was significant about the PC/AT, as near as I could tell at the time
it was put to work as a bigger faster IBM PC, still running all the
same old MS-DOS applications, still one at a time. And from
conversations I've had with folks who were doing Unix stuff on the
80286 then, they didn't think 80286 protected mode was progress w/r/t
the PDP-11.
Well, what did the PC/AT have that the PC/XT didn't? 1.2MB
minifloppies (although I saw those retrofit onto XT-class PCs), 16-bit
slots, a cascaded interrupt controller to handle the additional
interrupt request lines...and the A20 gate that let you get at another
little chunk of RAM up above the 1MB boundary while still in real
mode. Hmm. How many of these things do we consider historically
significant now, and how many will we still consider significant in 5,
10, 25, 50, 100 years?

Hey all. I think its about time I de-lurk and introduce myself.
My name is Bill, and I'm very interested in SwTPC and SSB stuff.
We had a couple SwTPC 6800 systems in my high school way back when,
and I'd love to see one again (or own one!).
After signing up for the Classic Computer Rescue Squad, I started
thinking, if a big old machine actually needed a rescue, what
would we do? I mean, maybe we should collect info on how big
these old things are, in terms of floor-space, tonnage, time to
dismantle, and so on. Then, when a rescue call comes in, we
could maybe decide if we can feasibly deal with it, and if anyone
actually wants the thing. If only three guys show up to dismantle
200 tons of vacuum tubes, it isn't gonna happen on-schedule. And
it's one thing to keep a mini in a corner, but not all of us can
arrange space for, say, a 360. So there are legitimate (if sad)
reasons that we might have to pass up a find.
Also, would it be good to have a rescue checklist? I can think
of a dozen things that might be good to do during a rescue, but
I'll bet I wouldn't think of half of it in the excitement of
rescue-day. I guess I'm volunteering to collect this, if you
all think it's a good idea and want to suggest things.
Okay, I'll close with the obligatory lists:
Want:
SwTPC 6800, CT-64, CT-VM, MF-68
EPROM burner
Have (willing to trade away):
DecScope terminal (ie: vt52), works
DecMate-III (don't yet know if it works)
Apple //c with monochrome monitor, some manuals, works
Radio Shack CoCo 2's, work
Defaced (ie: no faceplate) Amiga something-or-other,
with no monitor, keyboard, docs, or anything,
probably doesn't work
Have (and will keep!):
Radio Shack CoCo 1's and a CoCo 3, tech manual
IBM PC-XT clone
SwTPC S/09 (down with disk problems)
Lear-Seigler ADM-31 terminal (bought today!)
Of course, some of this stuff would have significant shipping costs
associated with it, unless you live nearby (central NC).
Cheers,
Bill.
<Also, a trackstar E for use with Tandy/IBM compatibles (Apple //e emulator
Trackstar 128
Funny I have one of them, haven't figured out what to do with it yet.
Not being an apple user it's an odd item in my collection.

...and the hard drive info in ROM.
But, you're right. The 286-386 jump was more significant than the 8088-286
jump, even though so of those 286 changes that you mentioned are still with
us that Pentiums are "AT" (not 386) class machines.

FWIW, my absolute favorite box of all time is the VAXstation 4000/60 or /96;
you can get everything out of the box quickly with no tools. In contrast,
it's only been in the last few years that I've gotten coordinated enough to
keep from mutilating my knuckles every time I go into a VAXstation 2000...

Bear in mind:
- Z180s now do up to 33MHz
- The average 128Kx8 15 ns SRAM
- is fast enough to run at 33MHz with no wait states
- contains enough on-board logic to do address decoding in a simple

The classic example of this and a conter arguement is the BeeGee Racing
aircraft. It was considered a widowmaker, as it nearly or did kill most
of the pilots that flew it!. A replica was made and the plane has been
flying for several years at airshows and doing remarkable acrobatics...
guess what it hasn't killed the pilot. What was lost was that it took a
healty respect and some knowledge of design and flight to figure out that
it wasn't so much the plane as the pilots that were the problem and they
have learned about the flight characteristics of a plane that was deemed
unflyable. Not to mention seeing a piece of flying history debunked.

Is the hard disk spinning up? I purchased two "new" (in the box with
shrink-wrapped software) UNIX PCs about a year ago. One of the internal
hard disks (a Micropolis 20 MB 1/2 height ST-506 interface MFM unit) did
not spin up, presumably due to stiction or a relative thereof. The
computer with this disk exhibited the behavior that you describe. The
other machine started up a "Welcome to the UNIX PC" application that
prompted me to insert the first disk of the installation media. On the
systems that I have (1 MB RAM, 20 MB HD 7300s), the system software was not
preinstalled, presumably to allow the version of the OS that was shipped
with the machines to be changed easily.
If you have opened the media, try booting the machine with the diagnostic
disk. If this works, the hard disk is likely to be the culprit. As Ward
Griffiths mentioned, the 3B1 uses ST-506 interface MFM disks, but it can
only access 67 MB without hardware modifications. There are utilities on
the diagnostic disk that you can use to test, format, partition, and make
filesystems on the hard disk. If you can't get the hard disk working with
these utilities, replacing it isn't too difficult. The ST-251-1 in my UNIX
PC isn't original, but neither are the GNU utilities, csh, and Perl that I
have installed on it.
If you're fortunate enough to have the (somewhat rare) Ethernet card or the
(somewhat more rare) TCP/IP software for it, be sure to check out the 3B1
FAQ before putting it on a network. There are some major security holes,
especially in the windowing environment. Brian Stuart has a lot of good
information (and the comp.sys.3b1 FAQ) on the Web at
http://colossus.mathcs.rhodes.edu/~stuart/3b1/3b1.html .

I purchased mine from a guy in Chicago who had a warehouse full of them,
new in the box. I doubt that many individuals buy computers and put them
away without using them (except for collectors), but many businesses like
to have spares on hand. Additionally, a lot of new "obsolete" machines get
written off and sold as scrap. I don't know, but I suspect that this was
the story of my machines.
If you would like to try the diagnostics without opening the software, let
me know, and I'll get you a copy of the diagnostics disk (from release 3.51).

Okay.... recently, there's been lots of "off-topic" stuff going on here
about computers... but I think that it's not "off-topic." In my mind,
there is no doubt that the early mass-produced CD-ROM drives (not the
origionals of 1984, but the ones that were made to be put into PCs, not
servers) are classic componets, even though many are of this decade.
In my opinion, the first 486 PCs (not servers) are classics... ones that
are still used, but classics... even though most of 'em were made in
like 1991-93... arguebly, early Pentiums (60, 66 Mhz) could be classics,
as they steped into a new era (superscaler arceticture) for the
mass-production market even though the Pentium chips wern't even on the
market until mid-1993... if you remember, in the "welcome" message, it
said that it was hard to state the definiton of a classic... but 10
years or older would do. I do not wish to offend the owner, but they
are one person, and they can make mistakes... and together, as a group,
the chances of making an accurate definiton are smaller with us.
Possibly (out for MUCH revision...) is the definition "Any computer
which has aged sufficently to be considered "outdated" by the computer
market and has historic signifiance, OR is 10 years old or older." The
one evedeint place that requires revsion is the "historical signifiacne"
but I'm not sure how to include that while still aknowladgeing the
presence of many of the best machines and componets that did indeed fail
in the process... but at least Wang's did eventually fall.... I can't
even rememeber all of the problems that they had...
Openly, innocently, and waiting for improvement (on my quote, not
the other stuff,),

Pack it away, sealed up, and find another 3B1 to work on.
I know a chap "down under" who has a LINC-8 in its original ply-
wood crate stashed in a storage locker. The thing has not seen the
light of day since it came off the line in 1968. It is one of 142
ever built.
What do we do with that example? Leave it packed away? Fire it

question, and one that harks somewhat to the same question asked by
those who restore, and fly, antique aircraft. If we fly it, there's

It looks like it's confession time here. The "no computers in the
dining room" is silly, at best. At this moment, I'm typing away on
my Linux box in the dining-room looking at least 10 computers, not
counting the micro I'm writing this on. There are another 4 in the
kitchen behind me, two of which have seen power this weekend. (6 of
the dining-room ones saw power over the weekend.)
Rules are made to be broken. Computers, of course, fit anywhere
you can find space for them. Even big ones. The bathroom, though,
is straight out. Too humid.

Given the marketplace today for "commodity" computers, what you buy
today is, by definition, obsolete as there'll be something "better"
along tomorrow. In a word - "why bother?".
Age, also, alone, does not make a classic. I doubt that the standard
run-of-the-mill '386 PeeCee will ever amount to anything except to,
perhaps, archaeologists who dig one out of a landfill. There were too
many of them made, and they were (are) regarded as "disposable". Look
at the construction - modern machines aren't made to be repaired any
more than a disposable cigarette lighter is made to be refilled. They
burn out, you toss' em, and buy another one.
Such was not always the case. Pre-PeeCee, machines were usually
constructed very carefully. I don't doubt for a minute that engineers
in the early '60s envisioned their creations happily hummimg away
in the year 2000 - the boxes were built to last. Pop the hood on the
latest thing to come down the 'pike - it's all ASICs, custom silicon,
and surface mount stuff on wafer-thin boards. In short - not built
to last. Nor is it designed to.
That, of course, is just my opinion. And a cynical one, too.
