//  Timex TS2040  /  Alphacom 32 Printer
//  ------------------------------------


//    WoS:
//    Peripheral: Timex TS2040 / Alphacom 32 Printers.
//    Port: ---- ---- 1111 1011

//    The TS2040 is wired as a z80 I/O port, selected by A2 being at low level and A7 being at high level. No other
//    address lines are recognised. To send information to the printer, use: OUT (FB), A - opcode D3 FB, assuming the
//    data is in register A. The data bits have the following meanings:

//        (D2) High level means stop the motor, low means start it.
//        (D7) High level applies power to the print head.

//    All these lines remain in the state they were last at, until new data is sent to the printer. At switch on, or
//    after pressing the feed button, D7 is set low; D2 is left high once feed is finished. The other data lines are not
//    used.

//    To fetch information from the printer, the z80 instruction: IN A, (FB) - opcode DB FB; will put the data into the
//    accumulator. The following bits are used:

//        (D6) Will be read as low if the printer is there, high if it is not, and is used solely to check if the
//        printer is connected. (D0) This is high when the printer is ready for the next bit. (D7) This line is high for
//        the start of a new line.
