All good questions, that are not readily available. I haven't seen any English manual,
only a Russian one.
You might post your questions to the Ectaco Forum:
Jerry may be able to obtain some of those answers.
P.S. When you first click on a thread, you will be redirected to the Ectaco main page,
just use your browser's back arrow to return to the forum and select the thread again,
you will then get there.
