-To program a blank EPROM, press '2' to load the image from disk, 'B' to confirm that the chip is blank, 'P' to program it and 'V' to verify that the image was, in fact, successfully programmed.  Oh, and if for some reason you weren't able to track down the correct datasheet, you can still try by starting with a programming voltage of 12.5V and increasing it if if the chip fails to verify correctly.+To program a blank EPROM, press '2' to load the image from disk, 'B' to confirm that the chip is blank, 'P' to program it and 'V' to verify that the image was, in fact, successfully programmed.  Oh, and if for some reason you weren't able to track down the correct datasheet, you can check {{:tools:eprom_programming_voltages.pdf|this}} out; failing that, you can start with a programming voltage of 12.5V and increase it if if the chip fails to verify correctly.
  
 The final option worth mentioning is the programming algorithm; in most situations, the 'Intelligent' mode should be fine, but to program some of the older chips you might need to select the 'Normal' mode. The final option worth mentioning is the programming algorithm; in most situations, the 'Intelligent' mode should be fine, but to program some of the older chips you might need to select the 'Normal' mode.
