I had intended to get the second edition of "Tandy's Little Wonder: The Color Computer, 1979-1991" printed so a few copies could be sent to the CoCoFest this weekend. I got notified a couple months ago that I'll be deploying to Afghanistan May 8 through mid September and just couldn't get everything done! It is now ready, but since I'm leaving soon I can only offer to e-mail the 4MB file to those with a PayPal account. I'm asking $12 for the book e-mailed to you. Of course it's copyrighted and I ask that the file not be shared with others. You may keep one electronic copy and one printed copy for your personal use at all times. I can only fill orders through Thursday, May 4th!! Sorry about this, but Uncle Sam sending me away means I have to limit to PayPal and e-mail. I'll offer CD-ROM versions for $15 (sent anywhere in the US) and possibly a hard copy when I return.
