similar blank PROMS made by another, then
it is okay to leave configuration set to the
PROMS you are actually programming. You
need not change configuration just to read the
originals.

A warning message gives the PROM type. If
the ESCape key is pressed the process is
aborted. If the ENTER key is pressed the
process goes ahead.

The example given will copy a 2764 in the
ZIF, addresses 00000 to 01FFF to USER-
RAM addresses 02000 to 03FFF.
