So, when can we pre-order the CD with your software + database Alain? 

@Jose, please let me know when you have your page ready and I can link to it on the main site.

I have an eBay watch page: http://www.ismenio.com/ebay_watch.html
But I haven't updated it in ages. I did manage to save some auctions, but I don't have them in a fancy searchable database like Alain's. One thing I was going to do was to have an archive of the full eBay page on the site but I didn't have time to continue that project. Also, after seeing many scam auctions I was concerned about people misusing the pages 
( http://www.ismenio.com/scam_auction.html )

Best regards,

Ismenio

Hi Alain 

Congratulations -  this looks a very impressive and valuable tool! 

One of your screenshots shows pretty well all the manufacturers. How do you determine which models you will collect data for? For example, presumably you don't collect full info for 'very common' machines (eg all CC7 sales)?

Best wishes

Hi again Jose,


Quote from: Jose on February 17, 2006, 02:26AM   

my English is not the best, therefore some things i not understand in first reading - so sorry :-)

No problem, mine is also far from perfect !


Quote:

If the ebay-screenshots are live, than you see this application for only 3 months. Than the article in ebay you did not see anymore. But you save the history auctions, or?

Yes, I save in a database table the computer's type, the seller and buyer aliases, the ebay id, the price, the date and sometimes a comment, for example "not working" or "with case" (because it raises the price of Mephisto Exclusive and Modular computers)
The screenshot I displayed is the form I use to save the auction's information : I fill automatically most fields of the left form and just have to enter manually the computer's type, and of course the comment.


Quote:

You did a great job. My Respect for your program!!!

Thanks a lot,

Best,
Alain

I love people, who can program with c, c#, c++ or other languages. I still learning c++ - but i start a few days ago. I only know about xhtml, css and a little bit php and mysql.

You did a great job. My Respect for your program!!!

Hi Mike,
interesting figure... I have to improve it ! I'll add a feature to parse the feedback page and check items not already in the database. Of course, I'll have to build of first class buyers... I already have a few names

You did program this with C++, or? Very excellent! The screens from the ebay Auctions are Screenshots or did you access on ebay LIVE

Hi Jose,
1. The application is written in C# which is a lot faster to program for form-based applications linked to databases.
2. Ebay data is live data : my "new" application is in fact an Internet Explorer bar which is displayed in the same place than history/favorites/...
So when I browse ebay, I just have to click on the "Mephisto I" icon in my toolbar and my "ebay band" appears and is able to parse the current html page.

I used to host IE in my first application but it was less efficient : when I received an email from ebay about new items in one of my searches, I had to copy manually the URL to my application. Now, I just follow the link, click on the Mephisto icon and add the item in my custom favourites list.

Best,

Alain

PS : I don't intend to put my database online so you can go ahead with your project, there won't be doubles.

Hi Alain,

wow, great Job! You did program this with C++, or? Very excellent! The screens from the ebay Auctions are Screenshots or did you access on ebay LIVE? you didn´t or?

I access on a mysql database and i feed this with a php-blank. And you can access all datas online with different criterias. But i take only ebay Auctions with rare computers. Otherwise i will be to much. And only the rare i find intersting. 

But if you put your database online - i would abort my work! Else we will do it double. What do you think?

hello Mike,

oh that is great if you have listings from 2005 and before! I will happy about it

Hey I recognise some of those people. 

Jose I print off the listings from the most interesting/significant sales so sometimes I can fill in details, or occasionally add to Alains list.

From what he shows though I would say that that Alains method captures around 80% ? Which is fantastic.

Hello Jose,


Quote from: Jose on February 16, 2006, 10:35PM   

i still working on a homepage, that lists all sales of rare chess computers. Now i see you have a database of those? Did you have it on your Page? Is there a link? I don´t want do the same as you.


No, my database is not on line, I am too ashamed of the wrong references for many computers 

Here are a few details : I have a SQL Server database on which I built two applications :
1. A standalone application (historically the first) which I mostly use to make queries as I don't have reproduced all its features in the second application.
2. An Internet Explorer bar which I can open anytime I am browsing on ebay. I am using this bar for two things :
  • Add a "favorites" feature with which I follow sales on which I don't want to bid (this allows my ebay list to be smaller and to contain only the post interesting sales
  • Track the finished sales, both from my custom favourites list and from ebay's list


Here are a few screenshots :
1. Internet Explorer with my custom bar


2. Mike's acquisitions in february 
Sometime, I also use the feedback's page to add sales which I have missed (I don't follow all sales)


3. The "Top" sales


4. CC1 sales : both succeeded and failed


Best,
Alain

In my database you can search for name, price, offers, buyer, date etc. (with screenshots from the auction)

I think in few weeks i´ll be ready. But my start point was in the end of the year 2005 - all before i didn´t have. But with help from you or other friends  i can complete my database!

Hi Tom,

I'm glad you joined us! It's always exciting to make new friends in this hobby.

CC1s don’t seem to be as rare as I thought they were so hang in there and you’ll get yours at the right price.
Sometimes I get emails from people offering computers so if I hear something about a CC1 I’ll let you know.

All the best,

Ismenio

Alain, thank you so much for the info!

As much as I want a CC1, I don't think I will go overboard like the one auction that went for $1300!  I know I can keep my bidding within bounds, thanks to yours and Ismenio's helpful information.

I really wish I had the ability/luck of Dick Schneiders and Mike Watters and others in winning stuff on eBay, but usually I am just the one who ends up paying full price for everything.  Someone has to keep the economy going!

Hey, if anyone here is thinking of selling a CC1, let me know.  I am willing to pay a fair price, not looking for a bargain.  I believe in being honest and fair with all of my dealings, as God has provided.

Anyway, just want to say that this is a great forum!  I am so happy I stumbled upon it a few days ago, and although a newbie, I appreciate all of the help I have received.  Thanks again for everything!

Best Wishes,

Tom

CC1: I have seen prices between 11 Euros and 1300 Euros 
11 Euros was a "15$ buy it know" by a seller who did not know the value of the computer.
1300 Euros was a  by a buyer who did not know the value of the computer (http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewItem&item=8746796035)
More seriously, 4 (at least) sales between 250 and 450 Euros in 2005. A CC1 proposed at 600, then 500, then 450 and then 400 euros in Germany did not sell.

CC3: prices between 30 and 300 Euros, around 15 sales (may be more) in 2005. average price around 100 Euros.

Best,

Alain

Tom,

just name a few computers, and I'll be glad to give you the information I have about sales of these models on ebay (if they are not in the many holes of my database).

Alain



Alain, Thanks!  Could you list what sales info you have for the CC1, and the CC3?  Thanks again!

Hi, where can I find Alain's database?  I am a new collector and would like to have a reference on current prices.  Thanks!

Have you guys seen this new eBay feature? It lets you research average price for items that have been sold for the past 90 days. This should be interesting in researching chess computer sales, though I would still rely more on Alain’s database as he has data going further back

Link: http://pages.ebay.com/marketplace_research/index.html

From the page:

What can Marketplace Research do for me?

For Buyers - Track items you're interested in purchasing and view the average sold prices for those items.

For Sellers - Access up to 90 days of eBay historical completed items data. Understand the demand for items you're planning to sell with charts trending average bids per item, number of completed items and more. View top searches within a category or the entire site to see what buyers are searching for.
