Put me down for 1 set.  Sounds like a project I'd like to do.

Me, too boss!

awesome,

I should have boards in about 2 weeks - still have to find many of the parts,
but I think I have the hard ones (8008 and 1101) -  most of the rest is pretty
conventional 74xx series.  The original units used a zener in a funky package
for over voltage protection, witch I doubt can be found very easily, but there
are modern equivalents.  watch my blog as details unfold

Also I've promised Evan that MARCH will get a set of bare boards for free.  It
will be up to MARCH to find the parts and build it up into a museum piece.

Aren't some of the components near unobtainium ?  BTW, I have a set of Mark-8
boars here waiting for the opportune moment to begin that project.

...

the 8008 is most expensive, but not really that hard to find -  I think the
prices people are getting on ebay are way to high as Intel made them into the
80's. American Microsemiconductor has almost 5000 1101 SRAMs and are asking
under $4 each.  The rest of the TTL stuff is basic 74xx - which are available
from unicorn electronics and other sources.

If MARCH needs volunteers to help build their set, I can help out.

So I was poking around on Intel 4004 and came across materials
on the first 4004 implementation, the 141-PF calculator.

http://www.4004.com/2009/Busicom-141PF-Calculator_asm_rel-1-0-1.txt
(Explore 4004.com if you haven't)

I was surprised to find that the software written as a interpreter; an engine
written in Intel 4004 machine code that processed a set of calculator pseudo
instructions. I really expected a brute-force native machine code
implementation.  I suspect I highly underestimate the software engineering
concepts that existed before the microprocessor, which would have yielded such a
sophisticated implementation right from the get-go on the 4004.

Hope you find this interesting also.
There's some very cool stuff being done with visual simulators of old processors
too, which is how I got down this path.
The Visual 6502 project is linked from 4004.com near the top,
if you haven't seen it, its worth a look.

I've been thinking some about that also. Since Dave McGuire is likely
bringing the big stuff I would do something different this year. I'll
go for our family computing history. Have the slide rule, mechanical
adding machine, books with tables to show parents computing. Then funky hand
calculator that doesn't do floating point, OSI computer, & TI professional
PC with IBM compatibility board for my early computing history. 3B1
for my wifes. Not that our computing is that special but the progression
is a reasonable show of how it progressed. Sorry, can't bring the
UNIVAC my mother did some work with.

Mechanical adding machines are Sears and Underwood Sundstrand 10140. Not
the most fancy but the Sundstrand can do shift and add multiply.

If anybody thinks its a bad idea let me know (conflicts with your exhibit?)

The other options would be card reader with a PDP-8 showing batch programming.
DEC had mark sense cards where you could do your basic programs with a #2
pencil on punch cards then run them on THE computer. It could also do
normal punched cards.

The last which is risky for completing is an 8/L with third party LINCtape.
Since I haven't done anything with it yet other than collect some needed
repair parts who knows how long it will take.

   Software technology didn't begin with microprocessors, you know. ;)

   Before the microprocessor era, the *smartest people on the planet*
were working on computers.  There were extraordinarily elegant
algorithms, data structures, etc in existence well before the 4004.  In
fact, most of what we have today in modern software traces its lineage,
sometimes with almost no modification, back to the pre-4004 era.

   Dig back into the history of those days, and prepare to be amazed.  I
grab every 1950s and 1960s computer technology book I can find...there's
a lot of overlap, but between all the authors' different viewpoints, one
can get a nicely-rounded picture of what those guys were doing in those
days.

Yes I should!
Got a few recommendations?

Agreed. When I went looking for 8008s, I found that you can pick them up for
less than $20 apiece, especially if you're willing to take the AS-IS gamble. I
picked up three for testing and found all three to be functional. Two were
"desirable" gold-top purple ceramic packages from Intel, went for $16 for the
pair.

I'll see if I still have the link, but someone sent me one to a surplus
electronics place that was selling "remarked" 8008s (in-house numbered)
guaranteed to be working 8008s for a good price.

Thanks,
Jonathan

I would not mind seeing the LINCtape, since I have a LINC tape drive without
cards. Anything "LINC" is scarce. The 8/L and LINCtape is not on your site
apparently, so I don't know if it could be carried with your intended exhibit.

Actually, there's a number of steam and old-engine organizations in say a 100
mile radius of Infoage, which would include west PA and NY state north of NJ.
Some have their own grounds, acres with resident equipment and facilities, and
with members who have their own equipment. Most of these guys have
kilowatt-class stuff, but some have tens of KW or more.

It's not unimaginable for InfoAge to host such a group which would include some
kind of vintage power generation - if InfoAge decided it fit within their
mission and Camp Evan history. I imagine the WWI Camp Evan generated its own
power.

Entirely my opinion of course, I'm not an InfoAge or MARCH officer. But I've
spent time visiting such organizations and attending their shows. Technology is
technology, I'm a technologist.

Web sites like smokstak.com have event calendars. Anyone interested can see
what's coming up and attend accordingly, they are inexpensive. Upcoming is a
show Jan 19th in Bangor PA (north of Easton) on the 19th. Long Island in
particular has a lot of old power generation stuff and groups that operate and
own it.

Once again Jeff B. and I spent several hours working in the storage warehouse
today. We built three shelving units and cleared stuff off a fourth. Most
important, we cleared a substantial amount of floor spaces, by moving some large
boxes from horizontal pallets onto vertical shelves. We'll be back at it 11am
next Sunday and we have a specific plan for how to proceed. There is a long
center aisle that's almost "finished" in being converted from piles of "stuff"
into organized shelves. This is a milestone.

I don't speak for OMARC or MARCH. But I've attended both events in 2012. (OMARC
had a couple hamfests.) My experience was that the hamfests were self-contained
at the Diana site including parking and food. I suspect it would be a benefit
for OMARC to coincide with VCF-E. I'd encourage the two of them to coordinate,
compliment their advertizing if at all possible. SInce both derive income from
attendence, it seems to me: "Sauce for the goose is sauce for the gander".

   For "the horse's mouth", there's really no way to beat "Collected
Algorithms from ACM".  It's a bit like reading an encyclopedia, and it's
extremely dense information, but it's great stuff.  Basically all the
algorithms we know and love, in the form in which they were FIRST
published.  The classic sorting algorithms, for example...reading the
articles their developers wrote to introduce them to the world, along
with example code (sometimes pseudocode), is very enlightening.  That
set of books is very expensive, but worth ten times the price.

   For the architectural side of things, "Parallel Computing" by Hockney
and Jesshope is possibly one of the finest books I own. (and, forgive
me, I own quite a few)  It's not about stuff like "clusters of Linux
boxes"...it's about parallel*ISM* in computing, in the way that an
eight-bit computer processes eight bits in parallel, or two bytes in
parallel (typically) when doing sixteen-bit math, etc.  There are
varying degrees of parallelism everywhere, and that book taught me how
to recognize it.  It also includes some case studies and in-depth
descriptions of some computer architectures.  There are very few books
that I can recommend as highly as this one.

eBay seller id "tvrsales" is currently selling property STOLEN from the 
Vintage Computer Festival.

If you are planning on buying anything of a vintage computer nature from 
eBay seller "tvrsales" in Stockton, California, please know that you are 
most likely BIDDING ON STOLEN PROPERTY.

The VCF Archives were STOLEN by Tri-Valley Recycling (eBay ID "tvrsales") 
in cahoots with the landlords of the building where it was sold.

The sordid tale can be read about through lawsuit material already on my 
website for download:

http://vintagetech.com/download/lawsuit/

I encourage everyone to read through the letters and especially the 
affidavit to see the absolute criminality of these vultures.  I am 
continuing to upload more material as I have time, but the basic story is 
there.

The court system was absolutely useless, as were the police and sheriff.  
I am having to sue for conversion, fraud, racketeering, unjust enrichment, 
and probably other charges as I continue my research.

I am here to tell you right now: Anyone on the receiving end of my stolen 
property is going to be entangled in this mess one way or another.  
Therefore, my suggestion to you is that YOU SHOULD NOT BID ON OR BUY 
ANYTHING FROM TRI-VALLEY RECYCLING IN STOCKTON, CALIFORNIA.  If you do end 
up with my stuff, you will become a part of the lawsuit in some way.  So 
if you don't want to have legal issues to deal with, stay away from 
anything they are selling.  I think I have made myself redundantly clear 
here.

The full story will come out in time.  Right now I'm re-grouping for my 
next legal attack.  Yes, I could use assistance, especially if you have a 
law background and can do research for me.  Sure, I could use money, so 
send some if you got it.  I don't need attorneys.  Attorneys are useless 
in the capacity that I am acting.  I'm doing this the proper way: myself.

My entire career as a computer historian has been destroyed by these 
hyenas.  Now I have to sit here and watch as they auction off 25 years of 
my life's work piece by piece.  Don't be caught in the frenzy when the 
lion shows up.

Guys -- as you all know I am very close friends with Sellam (as are a few other
MARCHins), and so I and maybe one or two others know much more about the
situation that we cannot and will not discuss. Don't even think about asking me
for details.

Keep in mind that the legal process is very complicated, it's full of
interpretations, and there are multiple sides to every story.

But as Sellam wrote, the situation is ultra-delicate. I agree with his
assessment that it's best not to get involved in the transactions.

So it's best if this news NOT sink into a thread where all of us non-lawyers
speculate based on information from one party's email.

I am glad he told us, I was watching some of these auctions.  Ug, what a
nightmare.  I really feel for Sellam here, he's a great guy.

This makes me sad.  I know the collection has been a labor of love.  It is
heartbreaking to watch this unfold.  I personally don't see how I could ever
enjoy any of these items taken from Sellam, no matter how desirable.

Boards are expected to arrive next Monday.  I'm still weighing details of the
early adopters plan, but I'm leaning along these lines.

Assuming that board pass the eye test and some basic mechanical checks, I'll
probably accept payment for a shipment on the next Saturday or Monday after
board arrival for those that want the best price, and are willing to risk
untested HW.

Then I'll ship a second wave after two more weeks, still with reduced pricing,
but not rock bottom pricing.

After that, I'll go to a standard price that I can live with going forward.

Just to give you an idea of pricing range I'm thinking about is in the range of
$200 to $300 for a six board set, with no components.

SCELBI computer sold kits, as well as build up computers.  Be aware that
building a chassis for the SCELBI 8H can get surprisingly expensive, depending
upon how close to a production system that you want to make it.  For a bare
bones setup kit type setup, you'll need 10, 44 pin edge card connectors, and +5v
and -9v power supplies, plus some switches .  You will need wire to connect the
power supply and front panel switches.

For a more authentic "production" system, SCELBI used 14, 78S11 relay sockets
for I/O and a total of 16 edge card slots.  Also, each card had card guides in
production systems.  The power socket is a 78S4 and the plug is a 86CP4.

The chassis is similar to a BUD AC-413, only 3.5" high, instead of 3".  Cory is
looking into the cost of getting a custom chassis made that closely matches the
SCELBI original, along with an authentic looking anodized blue front panel.

I've ordered a set of edge card connectors - once I confirm that they will work,
I'll post the part number.  Also, I believe I have identified the correct card
guide, but need to confirm that before I publish the number.

I think that all existing SCELBI 8H documentation, including assembly manuals
and schematics can be found online at one of the following sites.

I'm repeating this entry on my blog, and will share more information there, as
this project proceeds.

conventional 74xx series.  The original units used a zener in a funky package
for over voltage protection, witch I doubt can be found very easily, but there
are modern equivalents.  watch my blog as details unfold
