My program PCBSynergy will program a 570 Zevatech, it basically replaces Flexprog and runs under modern 32bit Windows environments.
It is located herehttp://members.iinet.net.au/~sarason/
As Marc pointed out joining the Yahoo group Zevatech is a good thing as there are many posts of Zevatech Technical support.
The program You are trying to locate is called EPU, and when you find a copy for the 570L could you send me a copy too. The Flexprog program
basically reads in a Text file to generate the Zevatech *.P5A file but without multi-panel support. The EPU program then adds this in within the *.P5A program.
Any other questions, I am happy to answer directly from my email or through the Zevatech Yahoo forum, I only very ocassionally log into this forum
