I checked for Linux disks online and saw some older ones at Amazon.
I hardly read printed stuff anymore, but the bookstore angle comes as a welcome surprise, and I just might want to give them a visit.
Meanwhile, I will make one more attempt w/ online downloads using ITguy's promising link.
Thanks.
1492, I tried many of those settings. No two websites are alike, and invariably you need a quick revert to normal icon (Blank Your Monitor has this) so you can see what is often hidden w/ hi-contrast black settings. Also, having the enlarged text wrap within the borders of your monitor is a Direfox feature that Chrome does not match.
