This article is from the Mongolia FAQ, by Oliver Corff with numerous contributions by others.
* Research-type programs for MacIntosh machines, produced by the
Université de Nanterre but never made publicly available.
* One classical font is offered by Ecological Linguistics for Mac
* A commercial font package is available for extended Cyrillic by
Linguist's Software for both the Mac and PC worlds.
* One apparently free Cyrillic font package for Mongolian is
available from www.magicnet.mn, it is intended for Windows3xx
users. Numerous reports were received that the system, once
automatically installed (there is no manual installation process)
replaces system fonts and keyboard drivers in an irreversible
manner so it is difficult to use this font on an occasional basis.
* Daniel Kai's XenoType Technologies' Inner and Outer Mongolian
TrueType (and Postscript) fonts for the Mac (as well as Soyombo,
Phagspa) in the computer systems for Classical Mongolian. This
system gets good reviews.
* MBE -- Mongol Bichig Editor. Written in Taiwan and released in
1995, this editor for MSDOS system provides true vertical display
and editing as well as 48-pixel and 96-pixel bitmap fonts for nice
printing results. The awkward editing behaviour and the feature
that everything between whitespace is regarded as one input and
editing unit (one cannot delete a single letter, only a complete
word!) make it a bit difficult to use. For documents in the
pageno<10 range, like short letters etc. the system provides a
simple interim solution until really powerful systems emerge.
