MaxLoader User’s Guide

5.Insert the 27C010 device into the ZIF socket. After inserting the part, make sure that the socket handle is down (close) to secure the chip.

See the illustration below:

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.

7. Click on the Program.

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.
