High rigrunner, great job. What CPU board version do you have? Is it already a newer one with the U110/PAL 20L8? BR /PeLuLe |

Is it already a newer one with the U110/PAL 20L8? --- End quote --- I have 400901 V1.9 digital board and the programmable logics are all suffix 10 :- 400902-10, 400903-10 and 400904-10. I think they are all dated 20th June 89 but it's hard to tell from the pictures i took. If i take the covers off again i'll make a proper note of the labels. |

I have the same 400902/3/4-10 chips, but they are all dated 29th January 92. |

As far as I have understood Datron part system, the definition of the content is defined by the No (the Datron part number). The date just gives, the day/date, the PAl is programmed. So all of the named PALs should have the same content. /PeluLe |

I have used rigrunner's python script before to dump my 1281 but recently found it didn't match a physical read of the chip. The data was correct but PRIM and SECN data were in the wrong order in the complete nvram.bin file. I swapped the order when it creates the output file and it now gives me a dump which matches. I also used it with vxi11 so that line is at the top and can be commented out to go back to a different gpib controller. I've attached the very slightly changed file. |
