    yes, as the sfft has its own d3d part it may be free from such common bugs.


    i remember that glitch on the intel platform but don't remember if it is solvable. because i've dropped using voodoo cards with winxp/2k due to a raw drivers. the only recommended platform for win2k is amd and via333 in terms of compatibility. win98 drivers have much less issues.

    it's a d3d bug in the w2k drivers. i'm sure that the glide games won't expose it. what is your system?


    the w2k drivers have more bugs than w9x ones.


    also the most compatible system is via kt266/333. and Win2k 1.05.05 is not supporting 4-chip cards, forget about it. only 3rd-party drivers for win2k/xp are working with such cards. and again win9x drivers are much better just because 3dfx spent more time working on these.

    in the most cases chinese suppliers are good if you know the peculiarities. for example, aliexpress is not the right place to buy ic components as there's a lot of fakes and refs, although at a low price. also some kind of national habits may have taken place.


    i have another story with my usual supplier. we had quite a lot of deals in the past years and i have no beef about the quality of the components. prices are good too. this february i've made an order of 12pcs of some ic parts, quite expensive, about $70 each. but she (the representative i have a deal with) declared them with the wrong quantity, but with the same sum. our customs stopped the parcel because of the inconsistency in the actual quatitie and the declared.


    i notify her about that and we agreed that the parcel will be returned and they'll resend it with a proper declaration. eventually the parcel was returned but their customs stopped it as well (i guess because of the obvious inconsistency of quantity). and the circus began. at the beginning they avoided any talks about refund or resend. then i received a proposal for a partial refund. i said: not acceptable and i'll apply to the support team (we made a deal via alibaba). no effect, then i asked: why lose a good customer as i was? eventually they agreed to send the ic chips once again and i've got them recently.


    and applying to the buyer protection on alibaba is another kind of show. i provided all the invoices and customs notify scans about that parcel but they said: customs clearance is on your side according to the deal. i answered: look, there's a wrong declaration, i can't do anything with customs since it's declared wrong. they said: it's your business. and all the buyer protections passed away.


    the conclusion is: you have to risk it to get the bisquit.

    the latest update is: after i've sent them a letter with a link to that thread and a promise that i'll make some other posts in all available places to me with bad feedback, i got refunded 2/3 of the sum with an argument, they did a try and some expenses they had.


    frankly, i have no idea what exactly they did and what their efforts were.


    thus the good thing is: they're admit their incompetence and i got partial refund. the bad thing is: i lost some money and the worst thing i lost 2 valuable cpld chips from

    two mine q3d cards.


    just trying to be objective.


    maybe i have to risk it one more time. just have to find another one green card with a proper cpld chip.

    I was curious about the Mercury brick. http://www.thedodgegarage.com/…/q3d_merc_bottom_full.jpg
    I have two non-functional green 200sbi cards and the whole system consisting of 4 black cards and all the other stuff. So i had the intention to figure out how to run it as a brick. Found some data, had a conversation with mr. Tregemba (i guess you know who he is and you saw his video) and found that i should try to clone 05 version of CPLD from a green card in order to replace 04 version of CPLD on a black card. Also googled for some service which advertises themself as a chip crackers http://www.ic-crack.com in particular. I thought that it's not a big issue to dump the data from that old XC9572 CPLD as some magic special equipment exists. Btw they charge considerable amount of money for such services ($1.7k), so i thought that is a fair amount for such a work. Had some emails with them and they said that the succes rate is almost 100%.


    Ok, i desoldered two (one for destroy, the other one for testing, i thought that will help them to make their job better) XC9572 chips from my green 200sbi cards and sent to http://www.ic-crack.com, the address is:


    Room 3020, XINMAO BLDG,

    MinFeng Road;

    LONGHUA District;

    SHENZHEN City;

    China

    Postal Code: 518 131

    Attn: Crystal

    The complete parcel track is here: https://t.17track.net/ru#nums=RR158393666RU


    I made two payments in $1.3k in total as i remember and in a while i got the jed file and 4 programmed CPLDs and the story begins. The jed file has this header:


    DD XC9572XL_Q64*

    DM XILINX*

    QP64*

    QF046656*


    You may clearly see the XC9572XL device in QFP64 package with 46656 fuses. XC9572 (which populated on 200sbi cards) is incompatible with the XL version, has a different amount of fuses (41472) and different package thus different IO pins amount. That is complete nonsense and everyone who has enough competence with CPLSs will say that. And, as you may presume, all 4 chips they sent to me were non-functional. Each chip has reset input and it has low state, so the whole 200sbi card is in reset after the CPLD chip is soldered.



    I make them aware of such chips' behaviour and wrong jed file. All they said is that they don't understand why i can't program my XC9572 with their jed file, where i see that the jed file is wrong and such bullshit. Regarding the programmed chips i made some reversing of 200sbi card and sent them the pinout of XC9572 to help to see that the reset can't be low constantly: https://www.modlabs.net/uploads/gallery/blogs/1026.jpg

    See pin 36 for reset for example. Also it has CLK_IN (38) and CLK_OUT (14) pins and i made a test device with a clock generator and shot a video with an oscilloscope with the correct CPLD chip to make them see how clk in and clk out pins should work. Both these pins are in constant low state too in the chips they sent to me. I was very patient with my tries to explain obvious things.


    But that was absolutely pointless, they just do not understand what is reset and clock signals and what is low and high state in electronic devices. May include some screens from emails, that is ridiculous. It's obvious now why they behave in such a way.


    Sure, no refunds.


    So far i can't do anything about that case and considering my money and time is lost, moreover 2 green 200sbi cards are dismantled with no purpose. So i announce https://www.ic-crack.com/ company as scammers.

    P.S. Here's the file i got from them: http://zxc64.com/tmp/XC9572-15PC44-Anthony.jed
    It's the plain text, you may open it with the Notepad and see the wrong device in it.


    i've made my own tests and found that the combination of heatsink/fans is not enough for proper cooling. silicon temp goes to 90c. inappropriate. either use coolers as the card had come or use faster fans on these slim radiators. this is related to 2-4 chip cards.
