javatex – A Java implementation of TeX
At root, this is a ‘small’ TeX (memmax=64K), but a larger version may be built.
The implementation was in essence an experiment, and performance proved so poor that the author considers it unusable in practice.
Maybe you are interested in the following packages as well.
- vtex-free: TeX system and PDF support for Linux and OS/2
- knuth-dist: The current state of Knuth's contributions
- atari-cstex: TeX for Atari machines
- tex: A sophisticated typesetting engine
