To compliment the 8051 Training Module,  Alexan came up with an affordable programmer for the ATMEL AT89C2051 and AT89C4051 microcontrollers.

The ATMEL AT89C2051/AT89C4051 Programmer has a comprehensive set of features that allows you to view, program, erase and secure the data of an ATMEL microcontroller.

Equipped with a computer-interface, the computer-interface software allows you to:

Load or open hex files containing the code you want to program to the device.
Read the hex code from the device and store it in the program buffer for editing or
saving.

View and edit the hex codes in the program buffer.
Save any changes made in the program buffer to a hex file for use with other devices.
Check the device ID.
Erase all the data in the device.
Blank check the device.
Program the hex codes found in the program buffer to the device
Verify the programmed hex code in the device
Protect the device from accidentally reprogramming by locking the device so that the
code cannot be read from it.
