Does anyone know if there is a way to read the above TMS 8K PROM chips with a GQ-4X? I can't seem to find any equivalent in the device library. |

Do they have standard JEDEC pinouts? |

They are standard 24 pin DIP EPROM chips. |

If they are standard read them as a regular 27 series EPROM. |

Found some better info here. The one I want to read is the 2364A/4764 chip on the left.

Ok, not a standard JEDEC pinout. Simply make yourself an adapter to convert it to a regular 27 series pinout. |

Doh!!! I forgot about using an adapter. I bought one years ago, dug it out of hiding, and using this has allowed me to read the 2364/4764 ROM.
Thank you  |
