+This DMCA Takedown Notice applies to the material hosted by GitHub at
+the following URL:
+
+https://github.com/fabriziotappero/ip-cores/tree/processor_4004_cpu_and_mcs-4_family_chips
+
+I do hereby attest:
+
+1. The above identified branch of this repository contains materials
+authored by me and published to the OpenCores.org site under a
+Creative Commons "Attribution-NonCommercial-ShareAlike" Public License.
+2. Each of the files containing material I authored contains a
+statement claiming copyright for myself as copyright holder, and
+stating my OpenCores email contact address "[private]".
+3. Each of the files containing material I authored describes the
+license terms in brief, and refers to the detail found in the
+"doc/License.txt" file also included in the repository.
+4. The material I authored may be considered to be derived from the
+Intel 4004 Schematics, which were released by the Intel Corporation
+under a Creative Commons license. A copy of Intel's license grant is
+included in the repository in the file "doc/Intel_IPNC_License.pdf".
+5. This branch of the GitHub repository also contains what appear to be
+files from some other project (an AC97 implementation, possibly).
+These files appear to be licensed under the GNU General Public
+License (GPL) or Lesser General Public License (LGPL). A copy of the
+GPL and LGPL license are included as files in "doc/gpl.txt" and
+"doc/lgpl.txt". These files were not included in my source repository.
+6. When viewing the repository at the URL listed above, a license
+statement is displayed claiming "This code is free software; you can
+redistribute it and/or modify it under the terms of the
+http://www.gnu.org/licenses/gpl.html (GNU General Public License) as
+published by the Free Software Foundation; either version 2 of the
+License, or (at your option) any later version."
+7. By my good faith belief and understanding, the GPL and LGPL licenses
+are irreparably incompatible with the Creative Commons
+"Attribution-NonCommercial-ShareAlike" Public License under which I
+published the materials I authored.
+
+I do hereby claim:
+
+1. The presentation of the materials I authored under the banner of the
+GPL is contrary to and infringing upon the plainly stated license
+under which I published my materials.
+2. The presence of GPL- and LGPL-licensed sources in the same
+directories as my non-GPL- and non-LGPL-licensed materials is likely
+to create confusion and incorrect belief that my materials may be
+used under the terms of the GPL or LGPL license, leading to
+infringement upon my copyright.
+3. The presence of GPL- and LGPL-license descriptions in the same
+directory as the correct Creative Commons license description in the
+"doc/" subdirectory is likely to create confusion and incorrect
+belief that my materials may be used under the terms of the GPL or
+LGPL license, leading infringement upon my copyright.
+4. I do NOT authorize or agree to relicensing of my copyrighted
+materials, under the GNU General Public License or any license other
+than that stated in the materials.
+
+The files listed below were authored by me in their entirety and
+reproduced in this GitHub repository verbatim:
+
+* doc/License.txt
+* pcb/4004-master/i4004-master.pdf
+* pcb/4004-master/i4004-master.sch
+* rtl/verilog/alu.v
+* rtl/verilog/counter.v
+* rtl/verilog/i4004.v
+* rtl/verilog/instruction_decode.v
+* rtl/verilog/instruction_pointer.v
+* rtl/verilog/scratchpad.v
+* rtl/verilog/timing_io.v
+
+The file listed below contains a PDF copy of Intel Corporation's license
+grant for use of the Intel 4004 schematic and other historical materials.
+
+* doc/Intel_IPNC_License.pdf
+
+Any non-directory file not listed above is extraneous to the
+OpenCores.org repository "scraped" to create this GitHub repository branch.
+
+The OpenCores.org project from which these files were "scraped" is found
+at the URL below. Note that it may be necessary to register on the site
+(free) to download the project repositories; browsing the project and
+the repository does not require registration.
+
+http://opencores.org/project,mcs-4
+
+To remedy this infringement I propose the following actions:
+
+1. Remove from the above identified GitHub repository all of my
+copyrighted materials. Such deletion shall be performed in such a
+manner that all copies are totally removed from the repository and
+the repository's history. Merely performing a new GIT commit that
+removes these files from the head of the branch is NOT ACCEPTABLE.
+2. Take action to prevent my copyrighted materials from reappearing in
+this repository, to include but not limited to being "scraped" from
+the OpenCores.org site in the future, by restoration of backups, or
+any other action whether initiated by the repository maintainer or
+by others.
+
+As an alternative, the following actions may be acceptable:
+
+1. Remove from the above identified GItHub repository branch all
+material licensed under conflicting licenses, specifically but not
+limited to the GNU General Public License and GNU Lesser General
+Public License.
+2. Remove from the above identified GItHub repository branch the files
+containing the texts of the GNU General Public License and GNU
+Lesser General Public License.
+3. Remove from the above identified GItHub repository branch the
+erroneous license statement claiming the material is licensed under
+the GNU General Public License.
+4. Take action to prevent future mixing of files containing
+incompatible licenses and prohibit modification of the license
+statements contained in the copyrighted files and the copyright
+descriptions found in the "doc/" subdirectory.
+5. All file removal actions are to performed in such a manner that all
+copies are totally removed from the repository and the repository's
+history. Merely performing a new GIT commit that removes these files
+from the head of the branch is NOT ACCEPTABLE.
+
+Note also that my project repository on the OpenCores.org website was
+not the only repository "scraped" for inclusion in this GitHub
+repository. While some of the OpenCores.org projects are indeed licensed
+under the GPL, most are not. Most are explicitly licensed under the
+LGPL, which is contrary to the GPL license claimed by this GitHub
+repository. Others, such as mine, are licensed under terms clearly
+incompatible with the GPL. It appears no consideration was made to
+differentiate between GPL, LGPL, or GPL-incompatible projects when the
+site was "scraped" to produce this agglomeration of independent and
+individually-licensed projects. Thus this repository may be the target
+of further takedown notices for similar infringements.
+
+Now to the "i dotting" and "t crossing" (IANAL):
+
+*I have read and understand GitHub's Guide to Filing a DMCA Notice.*
+
+*I have a good faith belief that use of the copyrighted materials
+described above on the infringing web pages is not authorized by the
+copyright owner, or its agent, or the law. *
+*
+I swear, under penalty of perjury, that the information in this
+notification is accurate and that I am the copyright owner, or am
+authorized to act on behalf of the owner, of an exclusive right that is
+allegedly infringed.
