Wow, I could make a fortune selling all the stuff I downloaded off of Bombjack.
Serriously, if the guy (girl?) actually took the time to scan and compile the C128 PRG into a PDF, then it probably is worth *more than* $12.95, at least to the seller! That is a massive manual, so respect to anyone who would do this (unless they are just ripping the file from Bombjack in which case they suck big time).
I suppose a really well done pdf scan could be worth it. I don't remember if Bombjack has this, but most of those scans are pretty good. I scanned the Plus/4 manual years ago. Ugh... the doin' and the result.
Let us not talk falsely now The hour is getting late
