You are right. The wire only needed for m27c1000. |

im doing these and 27c1001 27c160 27c800 eproms. so permanently tieing the line is alright? i wouldn't think so. |

Yes. You can solder a wire from A23 to PCB back side on ZIF pin 24. So that you can easily change the EPROM without link the jumper wire. |

above worked without double write.
i will need to solder a access pin on pin24 becuase im doing a bunch of these |

Please download the latest R2.05 software.
Check the Double-Write check box too.
Do a blank check before write.
Also, try without external power first.

yep fails at same spot both chips.
ill try the above |

No adapter needed if your chip DIP32 package. |

Add this line to devices.txt:
Name="M27C1000",ID="XXXX",Class="27C301",Category="EPROM",MFG="ST",RVpp="5V";
However, you need put a wire jumper between address header A23 to ZIF socket pin 24. And make sure they are contacted well. |

It should be able to add this EPROM. Do you have datasheet of it? |
