A person could certainly write a script to parse a. So you can issue the appropriate commands to write data to the EEPROM or read from it, but it doesn't do this automagically. Bus Pirate is intended as a console device, giving you command-based access to the I 2C bus. Bus Pirate will work to read and write the EEPROM, but you won't be able to just load and burn a. It may or may not (probably slow if it works at all). I don't know how well a USB-serial adapter will work since ponyprog probably toggles the handshaking lines at a high rate. Check the documentation or look for the port options in the BIOS (you may need to enable it in the BIOS before it will work). It is unlikely that there is a DE-9 connector on the back panel, but there might be a header on the motherboard to which you attach one of these.

See: You might be surprised to see that your modern computer actually has a real hardware serial port. It's a one-evening project.Pony Prog still works on Win7 (so I've read).

You can build the circuit using wire-wrapping or point-to-point soldering techniques on a solderless breadboard, in which case you'll need a cable, or with your own pc board. The dongle is primitive, but it does illustrate the basic principle of dongle-protection technology.

If a match doesn't exist, the software refuses to continue and exits.

When the protected software runs, it first checks whether the device is present at the printer port and whether the code matches what you programmed. Only you know whatever was programmed in the device. You can then use it as a hardware-protection device for your valuable software.
Another important feature of this circuit is that, once you program the 93CXX device, the system becomes a primitive dongle. It handles only one MicroWire device-the popular 93C46's read/write operation as an example. Click here to download the software for this Design Idea. A sample demo program, secret.bin, allows you to practice the programming. A freeware executable program, Pseep2.exe, is available for this purpose. For many embedded-system-software engineers, it's routine and interesting. Once you settle on the hardware design, the main task is to write software. The MicroWire interface normally requires a pullup resistor on the DO pin, but such a resistor is already inside the PC, so it's unnecessary. Because control Pin 1's logic is the reverse of the logic level on bit C0, the software must take care of the inversion. These selections caused no problems in practice. It also ties together pins DI and DO and connects them to the Control bit (Pin 1), which can serve as input or output, thereby saving one pin. This design uses the chip-select signal from the reverse level of the control bit (Pin 17).

With PonyProg and SI-Prog you can program Wafercard for SAT, EEPROM within GSM, TV or CAR-RADIO. At the moment it supports I☬ Bus, Microwire, SPI EEPROM, the Atmel AVR and Microchip PIC micro.
Its purpose is reading and writing every serial device. The MicroWire chip uses the CS (chip-select), SK (clock-signal), DI (data-input), and DO (data-output) pins to control its read/write operations. PonyProg is an open source serial device programmer. No decoupling capacitor is necessary in practice. The eight-pin, tiny, serial EEPROM consumes less than 1-mA current in the active state, and the printer port's data pin can supply a few milliamps, so this design uses D7 (Pin 9) as a power-supply pin. With the EEClip programmer most of the common serial interfaces eeproms can be programmed (SPI, I2C or IIC, Microwire) even eeproms with SOP8 packages with. On the classic IBM PC, the data port serves solely for output, but the control port can serve as either input or output. The printer port comprises the 8-bit data, status, and control registers. These advantages come from the PC's printer-port resources and the architectural simplicity of the MicroWire serial EEPROM. The circuit also requires neither a resistor nor a decoupling capacitor. However, you still can use a cable if convenient-for PC printer ports behind the PC, for example. When in use, it directly plugs into the PC's printer port. It needs neither a separate power supply, or “wall-wart,” nor a cable. This programmer circuit contains no microcontroller, as most device programmers do. The circuit is so simple that any further simplification seems impossible. You can use a device-programmer circuit used to program the MicroWire serial EE-PROM 93CXX ( Figure 1). You can easily use a PC's printer port for serial-EEPROM programming.
