[Coco] [Color Computer] 1984 djvu conversion

[Bob Devries]

I have difficulty understanding why the PDF files of these magazines are so 
large.

I have scanned some of my copies of Australian Rainbow. All pages except the 
front and back covers are black & white, and I scanned them at 300 DPI. They 
are readable... as much as the originals were readable (but that's another 
story)... but they are not text searchable.

Of the 30 magazines I scanned, the largest PDF file size was 6939KB from 76 
pages (275mm x 205mm) and the smallest 1800KB from 60 pages.
