Hi,

I was poking around in Catakig emulator, looking to (maybe) fix what looks like a keyboard handling issue.

Anyway, I found the appleii reference online (for instance at: http://www.1000bit.it/support/manuali/apple/appleiieref.pdf), but it lacks the page 14 (between 31 and 32 in the pdf). All other sources I found exhibit the same issue:

Any place where I can find the missing page or an explanation of how exactly the keyboard is supposed to behave in an apple 2 ?

Cheers,

Different editions of the //e Tech Ref have slightly different
pagination...

It is not an issue of pagination. If you look at the links I provided, you'll see that the page is just missing in the pdf or the jpeg files. It seems that, in that particular scan, page numbered 14 from the doc have not been scanned (jumps from 13 to 15), and the resulting file have been spread all around the internets.

I didn't mean to imply that the page wasn't missing, only that my
edition of the Tech Ref is has page breaks in different places and
so doesn't exactly correspond to the missing page 14.

I think it's interesting scanning has these completeness issues...and
it's not easy to "insert" a missing page into a .pdf!

But also check out Sather's "Understanding the Apple //e" for even
more definitive descriptions of keyboard behavior (such as the strobe
bit arriving a little *after* the key code changes ;-).

Thx. I'll take a look at it. Note that I don't need 110% precise behavior as by looking at the Catakig code, it seems it doesn't even handle key depressed events, and I am sure that confuses software in the emulator. Specifically, it looks like each key is only pressed for 1/60th of a second.

Wow--that would certainly interfere with RT.SYNTH's operation, or
anything that uses AKD.

If your email address is valid, I can send you a scan of the two
pages in my book that contain "page 14" of the scanned version...
