6. Click on the highlighted cursor Blank Check.
NOTE: If an EPROM is not erased completely, it will not pass the Blank Check.
If an EPROM is damaged to begin with, it may not pass the blank check,
although it has been erased for a long time in UV eraser.

CAUTION: Do not touch the device while the BUSY green LED light is on
(programming is in progress).
After programming a device, the part is automatically verified. The Checksum
is calculated and displayed in the OPTION info. In order to verify your work,
read the programmed part again. If this Checksum value matches to that of the
programming checksum, then the 27C010 is programmed successfully.
Duplicating an EPROM from a master IC device
The following is an instruction on duplicating a programmed device. In order
to do so a source device and an erased (blank) target device are necessary.
Source Device: Programmed AMD 27C256
Target Device: Erased or blank INTEL 27C256
1. Make sure the MaxLoader is displayed without any communication error
(refer to programming section ).
2. Place the AMD 27C256 device into the ZIF socket.
3. Select the manufacturer and part names from the Select menu.
4. Click on the Read button. In order to make sure the device is read properly,
Click on the Verify button.
5. Remove the current chip from the socket and replace it with the erased or
blank Intel 27C256 device. Select the appropriate device from Select menu on
screen.
NOTE: You do not need to change the device information if you use the exact
same chip as the source device.
