Hello all,
As I'm embarking on the road to implementing a 65C816 system, I'd like to study the Eyes & Litchy book "Programming the 65816". I don't have Kindle (I'm a linux user), and I loath using A'zon - does anyone out there have a PDF version that they could provide for me ?
Thx, in advance.

The W65C816 Programming Manual can be found on
WDC's website as the copyright is still held by them but I'm
sure you've found a try-before-you-buy edition by now.
Cheers,
Andrew

No, they just send you to A'zon. Which is why I posted in the first place.
But NYWay, problem solved -
someone has sent me a copy.
Thanks !

There are two versions of the PDF in the wild. The older of the two has a number of errors that crept in during the process of digitizing the original. Around 2015, WDC sacrificed an original paper copy and OCRed it into a clean and searchable PDF, which is what is available for download from the 65xx.com site. You can tell which is which by the first page, which, in the 2015 version, is a reproduction of the paper manual’s cover.

Thanks to all of you. It was the last link in BigEd's post that I'd been looking for, but I didn't find it using the forum search...
I transferred one PDF to my 'phone, just before going to an appointment with the cardiologue (yes, I'm part of the 'senior', 'wrinklies', 'old codgers', whatever, age group), and was so engrossed in my reading I didn't hear my name called
Now set for the 16-bit adventure!

Thanks for that, I didn't realise there were two different versions. And I have the wrong one which I - of course - printed and bound several years ago.
I'd really like decent hard-cover copy for my library though.
[EDIT]The addressing mode tables line up correctly in this one!

I started with the PDF version, but also bought a paper copy because I like collecting old computer books. If you choose the right ones you can still learn a lot from them, not all the information is out of date and some of it just isn't covered in modern books.
