Almost forgot - I wrote that program for FAST memory quite a while
back. It's short and simple, so here's a copy.

/*
 * fast-mem-p - exit 6 (WARN) if there is more K of fast mem than
 *      the argument. Default is zero.
 *
 *      Copyright (c) this? Are you kidding?
 *
 * Typical useage would be something like:
 *
 *      fast-mem-p      2048    ; Have I got two meg or more of fast?
 *      if warn
 *              ; yes, do whatever setup you want here.
 *      else
 *              ; no, do small-time setup here.
 *      endif
 *
 * For more power, (and more size), see "enough", on Fish disk 29.
