Brief Explanation:
A very small digital circuit designed to be connected to the PC's parallel port and A windows based software provides the following applications:

1. Read and write data in various static RAMs. We provide this kind of RAM with a battery backup circuit that holds the data after power off.
2. Read data from various EPROMs
3. Program 89x51 and 89x2051 microcontroller series.
4. Load .hex and .bin files to the memory ICs.

You may download the last available version considering the license file from the download page. Note that without accompanied digital circuit you may just use the software for evaluation purposes. In this release "Diagnostics" section is available and have not been inactivated, so you may also use it for exploring the parallel port.
