Intel 8279 Keyboard Interface Info

MyndFyre · October 21, 2003, 09:38 AM

Does anybody have either the commands or a site where I can get the info for what bytes/words correspond to what on the 8279 Keyboard/Display Interface? I'm working with an old-school Intel SDK-86 for a class, and I'm not quite getting what I want.

TIA

You can't go to google and type "Intel 8279 Keyboard Interface" but you can come here and ask us for the information? Hmmm.

Be nice; this board could use any traffic it can get

I didn't find an obvious good first hit on google either so it'll probably take a while to google it out.

I found an obvious hit within the first five. It took all of two minutes.

Really? Which one? Maybe my google doesn't give the same hits as yours.

Edit: My five first are:

http://www.aldec.com/IP_Services/Datasheets/8279.pdf - a block diagram of an ip core

http://www.aldec.com/IP_Services/available_cores.htm - a list of available cores

http://www.cast-inc.com/cores/c8279/C8279.pdf - a friendly description of an 8279 ip core

http://www.cast-inc.com/cores/c8279/cast_c8279-a.pdf - pinout and block diagram of an 8279 ip core

http://www.altera.com/products/ip/iup/peripherals/m-cas-c8279.html - information on features and chip use for an 8279 ip core

None of the above give a listing of actual data values/definitions of ports/etc.

A search with quotes around it produces no hits.

Try this <http://www.csee.umbc.edu/~plusquel/310/slides/8086_IO3.html>.

ty Skywing, and in re: to Grok, I did Google it, and I looked through ANYTHING that looked pertinent at all, through about the first 10 to 15 pages of search results, spending about an hour on it. I also tried a few variants (I was looking specifically for commands), including "commands" and removing Intel. I also scoured Intel.com looking for a programmer's datasheet, but searching for "8279" returned nothing.

You have to know what to look for. I included the Google search link that I used to find the page I posted a link to (note that it's the first hit).

Well now that you have the info, case closed?

Just as Skywing found, that entry was the first hit on my search results of my second search. It took all of two minutes to vary my search pattern to find that. How?

Put "8279 Keyboard Interface" into the "with all of the words" field and click GOOGLE SEARCH. Voila, first hit.

Adron · October 24, 2003, 01:12 PM

Still means I spent 5 minutes clicking through links following the exact search string you specified without finding anything interesting :p

MyndFyre · October 27, 2003, 08:50 PM

Ahh, you looked for "8279 Registers"....

ty =)
