Are Sellers And Gammas The Same?

[agarol]

The saga continues...

Thanks to the kindness of several members here, I have a selection of dead cards including a dead 7272, a dead sellers, a useless v3, and some of the early public gammas (v1.2 and v1.4). I also have a selection of other os cards including titanium 1, didem, titan.

Back to the gammas: whilst the contact patterns on the 1.2 are different from the 1.4's, the contacts on 1.2 are the same as the sellers and the v3.

What is more interesting and probably more instructive is the fact that all the atmel based chips that I could find (7272, 6464, 3232) all drew between 3-5 mA at 5v, whereas all the gammas and sellers drew about 50mA at 5V.

So my current theory is that all of the gammas and the sellers are the same, and that none of them are based on an Atmel 7272 as has been widely rumoured.

I agree they are all one in the same gamma and seller and I think you had better look here and ;then look for another reason for your voltage mA outputs. Log into this site and click any links to any card and find these details below .But most of all notice the heading.

Do you reckon this site buys their cards from the Gamma team or Atmel?

My point is that the cards were probably purchased from the gamma team as it looks like they are selling gamma cards, not blank atmels.
If that is the case, how would they know the cards are atmels? Maybe the supplier told them the cards were atmels?
I mean, there has not been one legitimate documented instance where anybody around the world has actually bought an atmel 7272 and managed to turn it into a working gamma card, has there?
So at the moment, I choose to believe my own research, rather than the claims of a website. Maybe I'm wrong - if so, please provide me with some evidence.

There used to be a file here somewhere of how to virginise a 7272 by 007.4 and maybe running that on a few cards may shed some light on the situation. I'm searching through my records to find it. Because from memory after running it you did not need to reuse transport code as it was already in card. It will be interesting to see after running it what atr's we get.

that is a blank card and its the same with a .gam file loaded

Sellers
ATr 3B B2 11 00 10 80 00 02
that is a locked card which shows as AT88SC0204C (Atmel memory card) Fixed eror.

No argument with your ATRs.

Which one are you suggesting is the ATR of a blank AT90SC7272? The answer is none of them is!

Still, the evidence that you can turn a gamma into a virgin AT90SC7272 is very scarce. Have you actually seen ANYBODY claim they have done it? ANYWHERE in the world, on any of the forums?

I haven't.

Could it be possible that the gamma code that has been loaded to the card be responsible for the increased current consumption??

Question for you agarol. All aussie provider cards after being programed with os bin, look the same. The only difference i can see is the 2nd bin file for each providers version and services. Would you agree with that?

Working card? What provider Cobra? PM if necessary.

Working card? What provider Cobra? PM if necessary.

Ill take a wild stab and guess Select from the rumors floating around.

[mickc]

the atr of a programed card can be anything the programmer wants it to be
and a locked atmel can also be made to give any desired locked atr
so are they the same
i think so

[N00b]

Ill take a wild stab and guess Select from the rumors floating around.

I think you may be spot on there.

Poor Select, what will they do now, maybe employ Austars technique.

The poor guys were trying to force some competition and try to give us a better deal, and now look what we have done to them..............

I was always one to back the underdog, guess I need to back them even more now.

I have been told that 7272 ATRs are similar to the ones you quote. I'm not sure that I agree that "3B B2 11 00 10 80 00 02 = locked 7272" is necessarily true. As you are probably aware, the "gamma source code" has that ATR and all it is doing is returning a fake ATR, and this is possible to do on any microprocessor.

Could it be possible that the gamma code that has been loaded to the card be responsible for the increased current consumption??

All the cards I measured had os's on them - in the case of the atmels, titanium, titan and didem.

What program to use to put new hsn prov00 prov10 on whitey or can only sellers do it.?

[machine]

Are sellers and gammas the same


NO, snigger snigger

Please tell us more......

Below is the AT90SC7272c OS Loader written by 007.4 - The script is used to load a new OS to a virgin or blank AT90SC7272c card. It turns the blank card into a Gamma - there are two versions of the file in the zip - one with a dummy Transport code and the other with the actual Transport code I was supplied by the card supplier along with the blank card.

Once unzipped the files can be read in Ultraedit or Notepad - They are well commented and 007.4 explains the process. (The files are VBScript files - I used WinExporer in a CAS3 to run the files)

[earlsdon]

Below is the Chinese supplied program to add the Atmel Transport Code to the AT90SC7272c. The zip includes pictures explaining how to undertake the process. However, I found it was not easy to follow as I am not able to read Chinese

[markfs]

The one thing that most of you have not observed in your search's is that there are several chinese manufactures making the at90sc7272 card as with all clones some will behave differently to others
