-<p>Work-in-progress repository with output of altium2kicad conversion
-of the Cryptech Alpha rev03 board.</p>
-
-<p>The conversion was done using 'convert.sh', with the Altium Designer
-project files from</p>
-
-<p>https://wiki.cryptech.is/browser/hardware/cad/rev03</p>
-
-<p>and the altium2kicad project from</p>
-
-<p>https://github.com/thesourcerer8/altium2kicad</p>
-
-<h2>Current status</h2>
-
-<p>NOTE: The latest stable KiCAD version as of this writing is 4.0.7 - it does
-NOT include necessary support for stitching vias. Install KiCAD nightly build
-to work with the Cryptech Alpha PCB.</p>
-
-<p>The schematics are mostly converted. A few components do not connect with their
-nets (e.g. C9 and C10 on sheet rev02_01), but maybe a manual overhaul will be
-needed anyways at the end of conversion. A bigger issue is that no components
-get footprints associated with them in the schema, so generating a new netlist
-won't work at all. The footprints exists in some form in the PCB, so we only
-need to figure out how to reference them properly in the schema.</p>
-
-<p>All the copper layers convert reasonably well. The challenges are mostly
-around filled polygons on the various layers. A python script (fix-pcb.py)
-modifies parameters to get a fairly close result.</p>
-
-<p>I'm currently looking into ensuring the drill hole sizes are right, and the
-non-copper layers have been largely ignored this far.</p>
-
-<h2>Issues</h2>
-
-<p>Two layers (Altium Gerber files CrypTech.G1 and CrypTech.G2) have fills
-that I have not been able to reproduce. I targeted not missing any copper,
-accepting that the KiCAD gerber fills reach more places, so add some copper
-on those layers.</p>
-
-<p>Drill hole sizes have not been checked. KiCAD seems to add ~0.85 mil more
-clearance around vias. This needs to be double checked but I'm hoping that
-we can just tolerate that.</p>
-
-<p>Importing WRL files (3D models) required some hacking of the altium2kicad
-tool that I haven't been able to work on upstreaming yet. Something is still
-not right here, but the board does have a fair amount of component (including
-the more special ones) in KiCAD 3D view.</p>
-
-<p>Another hack that has not been upstreamed is loading more of the source
-files, IIRC to get all component footprints properly converted.</p>
-
-<p>The KiCAD board does not pass DRC checks yet. I believe part of this is
-because design rule settings aren't (fully?) imported from Altium. Need
-to figure out the settings used for this project, and fix all drill sizes
-I think.</p>
