Here is a script for WinExplorer (by Dexter v>4.6) that will check the condition of a K3 card and then load an application.
You need a Phoenix interface at 3.57Mhz.
The K3 card has some timing issues so the delays are set quite high. This makes the loading go quite slowly. Depending upon your hardware you may be able to optimise the timings.
This script has been well tested and is safe to use.
Read the instructions at the top of the script.
