Ian Chadwick is the author of Mapping The Atari, which was — and remains — the ultimate
memory map for the Atari 8-bit computers. Mapping was published in two editions: the
original was for the 400/800 computers, then an updated version was later released for
the XL and XE machines. Ian also did a lot of documentation writing behind the scenes,
including many of Antic’s software manuals, and several manuals for Batteries Included and other companies.

“So I would write these little BASIC programs that would go along, and they’d POKE a bunch of memory locations, and at the same time they’d be PEEKing into other memory locations to see what would happen. And it was so much fun!”
“It wasn’t intentionally started out as a book, it really intentionally started out as a database of information for my own use.”
“They’d say ‘You’re the guy who wrote Mapping The Atari! You know, that turned my life around when I was 18!’ or something.”
“It took about two or three minutes to get the platter warmed up. Spinning up to speed it
sounded like a Lear jet taking off. Wooooosh! And it held six megabytes.”
