Success! The practice book is now on my device in nice clean large font. I can't thank you all enough, but JSWolf has been especially patient and kind. Now I'm going to buy
The Light Fantastic, convert it, and get started reading the next book in the series.
In case this may be of help to anyone who wants to try it also, this works very well as a way to get a secure mobi book onto an EBW-1150.
BEFORE YOU BEGIN:
A. Download mobidedrm and Calibre from MobileRead
B. Download Python 2.6
C. In Python folder, place a copy of the secure book in Scripts folder.
STEP 1: Remove the protection
Go to the Start button at the bottom of the screen, click Programs, Accessories, Command Prompt.
Type cd\python26\tools\scripts and enter
Then type exactly what is after the ... Scripts>
C:\Python26\Tools\Scripts>mobidedrm.py exactbooktitle.prc clearbooktitle.prc <PID
Hopefully, you will see this:
MobiDeDrm v0.04. Copyright (c) 2008 The Dark Reverser
Decrypting. Please wait... done
STEP 2: Convert PRC to HTML
Put a copy of the new book in the Calibre folder
At the command prompt, type cd\program files and enter
Type everything after the first >
C:\Program Files>calibre mobi2oeb clearbooktitle.prc clear2booktitle.oeb
(This book magically appears in c:documents&setting\owner as an html)
STEP 3: Finish
Open html, save as txt, then convert via EBW Librarian.
For large fonts, choose "advanced" and get the little drop-down portion when you "create book"
