Ok, I checked VT340 schematics.  Ok, I  need two ROM dumps:



512Kx8 2804 EPROM on E80 (firmware code)

32Kx8 27256 UVEPROM on E49 (character generator)



Yes, All VT300 series uses 8031 processor with DC7051 video controller
and 2681 DUART interface.



Thanks,

    Yes, I am interested in that. Please let me know when you made ROM
    dumps from VT340 boards.



    Do you still have VT125 board as well?



    Thanks,

    Tim
