<p>LON-CAPA works nicely (for development purposes) on a Pentium II, 20
gigabytes of hard-disk space, 256M RAM, and 400MHz. The consensus is though,
that this may only be adequate for a class of a dozen students. </p>
<p>If you are making a serious investment, you should join the LON-CAPA mailing
list by visiting http://mail.lon-capa.org/mailman/listinfo/lon-capa-users. By
posting to this mailing list, you can learn about the solutions have worked for
others. </p>
<p>LON-CAPA works on any Intel-based RedHat-compatible hardware. Unlike other
e-learning software systems, it works comparatively well on dusty old crippled
machines without much RAM or processing. </p>
