Have you built the test programs in a separate build tree from the
floppy monitor? If not, then it is very easy to get
cross-contamination and, for example, end up with you executables being
linked to the same memory locations as the monitor. The symptoms you
describe are consistent with the monitor being overwritten by the
download.
