That article refers to the size of the ELF object file. It has nothing to
do with the code size.

For illustration, I wrote a primitive preemptively multithreaded
"hello world" program for getting more familiar with the MVME147. Including
startup/initialization and scheduling code, I ended up with 520 bytes
of text, of which a considerable part is actually read-only
string constants (I admittedly relied on 147bug routines for
sending strings to the console, though).
