These are fully-described and contextualised at https://nabijaczleweli.xyz/content/blogn_t/008-amix-fonts.html
Pre-builts are available at https://lfs.nabijaczleweli.xyz/0013-AMIX-fonts/

You need:
	AmixInstallation.zip
	Amix/Installationsarchiv/amix_2.1.cpio.bz2
	usr/sys/amiga/console/{sunfont,topaz}.s
or
	amix_21_tape.zip

	usr/sys/amiga/console/{sunfont,topaz}.s
to land in this directory, and FontForge. potrace, ImageMagick, cc.

Bitmap fonts are not subject to copyright protection (they are not software),
but the original files are (they're software that encodes the font).
The result is unburdened by this.

fontforge needs to have https://github.com/fontforge/fontforge/pull/5138 fixed (or you need to fiddle with step 08).

If you have the prerequisites, run the executables in order, watch for errors.
The "too complex for me to understand" errors (one for sunfont, two for topaz) correspond to the spaces, which have no curves.

Hard strikes for all sizes in 02imagise.strikes (1..16) are generated.
The Unicode mappings are in 07-strike.map*.

The *-strike.bdf files are all a lie that we need to feed to fontforge as a bitmap font interchange format.
Use the *-56.bdf (&c.) ones.

In addition to those, you get:
  + *.otf      which include everything
  + *.sfd      which are the FontForge "project" files, if you want to export more formats this is what you want to use
  + *.allchars which list the characters in the font corresponding to all glyphs
  + *.pdf      which are FontForge demo files
  + *.pbm*     which are the per-glyph images for each size
  + *.svg      which are the SVGs for each glyph at 4x
  + *-montage* which are the demo images pasted together at 4x, 2px between glyphs
