    Code for the Nightfallcrew vhdl version is already posted, or have a look in the pdf "PLA Dissected", it's all listed.
    You'll find the VHDL code in the link already provided:

    Copy the part under "CÓDIGO: Bitte melde dich an, um diesen Link zu sehen."

    Then just compile, set the pinout properly and you have your jed-file.

    You'll have a pretty compatible version when done, if you don't want to spend 4-5 hours doing this (maybe 24 hours downloading software from Xilinx as the server is quite slow) then I suggest you just buy a U17 PLAnkton or maybe a RealPLA, that works a lot better than this almost ten year old non-refined "Nightfallcrew version", IMHO it's worth the money - or simply buy an XC9536 from eBay and you can use the already available file.

    As Brotboxfan's signature doesn't give any clue to the price I thought I'd just add that as well, at sinchai.de it's €15.99 (not available at the moment), shipping seems to be about €5.20 within Germany.
    Maybe they can be bought cheaper directly from Brotboxfan. :wink:

    Don't think there's much functional difference between RealPLA and U17 PLAnkton, SuperPLA V3 however has at least one area where it is less compatible.
    Robert Bernardo commented on the Denial forum about Ray Carlsen's experience - the SuperPLA V3 failed on a 326298 motherboard - U17 PLAnkton works!

    AFAIK there has been no failures at all with the U17 PLAnkton.

    U17 PLAnkton is €14 and European shipping (unregistered) is €3.60 for 1-4 units.
    Amigakit.eu sells SuperPLA V3 for €18.90 - it's however for other computers as well, shipping within Germany is €5.99.

    Got to get to work, someone google the RealPLA...

    Sorry for the English, I thought Google translate shouldn't mangle my writing.

    We are now starting a new batch of U17 PLAnkton, it has been very successful and compatible with all boards tested by customers, not a single complaint, over 300 pcs sold so far.

    When scrolling through comments (wondering why I haven't got a single e-mail notification about these) I see there are questions about the voltage levels. The U17 PLAnkton uses a XC9536XL which is a 3V chip, it's however run on a slightly higher voltage (within specification) to come closer to what an original PLA has - thereby making it compatible with for example cartridges using capacitors as timers. An original PLA doesn't leave 5V on the outputs but rather 3.7-4.2V, it's one of the details the U17 PLAnkton mimics better than some replacements.
    The timing is carefully balanced and it's within 2ns the same as the original Commodore PLA 7700. The time it takes to get from low to high (raise time) is another important feature that U17 PLAnkton replicates very well. For older boards that have a delay filter already soldered on the board there's the possibility to bridge the U17 PLAnkton to be fully compatible with that as well (or it might be slower than needed).

    Current price is €14.
