    Pour transférer des fichiers entre MSDOS et CP/M, il existe le fameux utilitaire 22DISK de Sydex. Il est vraiment parfait et permet toutes les operations
    sur les fichiers d'une disquette CP/M à partir de DOS.

    Z80 project..

    My first micro was a Z80 board. I used a National INS8251 USART, a Motorola MC14411 bit rate generator and a friends terminal to run it. Later I build a
    dumb terminal from scratch. Nowadays I can still run the board but I use an old PC with a VT50 terminal emulator program.

    Nowadays a advise to use a 16550A UART. That's the one used in PC's today. It's not the easiest chip to program but it has a build in bit rate generator (except fot the X-tal) and for all I know it's bug free.

    If you are looking forward some data or repair parts about this electronic card, you can contact me by e-mail at
