See Glossary for the special ways of editing of
the parameter line.
PRETEST compares a PROM in the ZIF with
the contents of the USER-RAM between the
START and END addresses. The purpose is
to check whether EPROMS must be erased
with UV light prior to programming. Bits are
erased all high, and may only be programmed
from high to low. The first location which
cannot be programmed is reported. If a
PROM contains locations which are already
programmed, but the PROM will accept the
new program, the message WILL BURN is
displayed If the PROM is actually blank it
contains all FF bytes - then the message
BLANK ROM is displayed.
