  1. Good evening,
    I would really like to run a trs-80 clone machine called DGT-1000 in this emulator, Brazilian version, I have the roms, but I can’t emulate them. The DGT-1000 was a clone of the American TRS-80 Model I microcomputer that used a Z80A microprocessor clocked at 2.5 MHz. Can you help me with that? I really like your work.

    • Nildo,
      For any questions related to the trs80gp emulator, you should contact the author of the program, George Phillips. In addition to being very knowledgeable and very talented, George is really nice and encourages anyone to contact him with any questions or if they need assistance. He, and his brother Peter, have both been very helpful to me many times. Go to his website and you will see his email address.

      • Hi Blair, thank you very much. I will go look for his email, and I hope that I can emulate this Brazilian clone of the incredible trs-80, the DGT-1000 from Digitus.
        Thank you very much, hugs.
