details. If all locations are programmed without error the following message is
displayed:

Selects type
of PROM device
Function
For PROMs less than 32K bytes, the DEVICE SELECT key selects the PROM
type when you use a personality module capable of programming more than one
type of PROM.
Each time the DEVICE SELECT key is pressed, the next valid PROM type for the
installed personality module is indicated by a lighted indicator next to the PROM
type printed on the personality module front panel. When the key is pressed on
the last PROM type, the first PROM type is again indicated. Press the key until the
desired PROM type is indicated.
The DEVICE SELECT key is inoperative if the installed personality module can
only program one type of PROM. DEVICE SELECT is also inactive during
programming, verifying, or ROM to RAM loading.
The DEVICE SELECT key clears any editing changes in PROMs greater than 32K
bytes.

Terminates current off-line
function or clears entry
Function
The CLEAR key terminates any ROM TO RAM, VER, PROG, or LOCK function
in progress and restores the display to the following:
IUP READY 000000 dd
where dd is the data value in RAM at address 000000.
Pressing CLEAR will also restore the display after some error conditions.
When entering addresses or data in display, modify, fill, lock, or load modes,
pressing the CLEAR key returns the field to the value it was at before the entry of
the new address or data. If no entry has been made, pressing CLEAR exits the
function and displays the IUP READY prompt.
