Then, I will gladly try to answer any questions that you (or anyone else) have. Back then, I and many Net54er's, discussed
the merits and/or questions regarding this subject.
To your latest question......simply because American Litho. was immediately forced to discontinue their 150 series Plank. It
appears about 50 cards got out in the market before this occurred.
I have to go out now, and remove some more snow from my 240 foot driveway.
