All you need to start with Atmel AT89 microcontrollers

This is simple development board for Atmel AT89 series of microcontrollers that uses ISP programmability I found in sixca.com. This is good start for learning with MCS-51 base projects.

To program chip:

    1. Connect ATMEL ISP cable to PC parallel port and power supply.
    2. Run ISP3.0 for Windows95/98/ME use ISP-3v0.exe and WindowsXP/2000/NT use ISP-XP.bat .
    3. Select your devices from drop down list menu.
    4. Click “Open file” to open hex file.
    5. Click “Write” to program device.
