Quoted from Coyote:Be sure to do a verify afterwards - if the chip wasn't getting enough power from the programmer, then a verify would catch any bits that weren't written right.
Also it can help to double and triple burn, and to catch some counterfeits, I always remove the eprom, wait a minute or so, put it back in with a cleared buffer, read in what's on the new chip, save it and compare it to the original file.
Quoted from Tuukka:With most programmers, the double or triple burn will not help, because the programmer first reads the eprom location and compares it with the data to be programmed, and skips programming if it is already correct.
Hmmm interesting. I guess that would explain why it sometimes goes faster.
