+bf2k+ Posted January 26, 2006 Share Posted January 26, 2006 (edited) Hi; I picked up another 800XL today and it is SOCKETED!!! Looks pretty clean too. I have 1 slight problem with it. Starting with key '7' and moving to the right, all keys to the right of 7 do not work. 1 thru 6 are fine as are ALL other keys on the keyboard. Weird huh? I am going to try swapping the keyboard with another one now, but I was wondering if anyone else had ever seen this behavior? Thanks Edited January 26, 2006 by bf2k+ Quote Link to comment Share on other sites More sharing options...
Rybags Posted January 26, 2006 Share Posted January 26, 2006 That would indicate that one or more of the contacts on either the ribbon cable or socket are dirty. Try giving the cable a wipe with some VCR head cleaning fluid. Quote Link to comment Share on other sites More sharing options...
+bf2k+ Posted January 26, 2006 Author Share Posted January 26, 2006 Well... Swapping the keyboard with another one did not solve it - neither did cleaning the ribbon and socket with contact cleaner. Back to the drawing board... Quote Link to comment Share on other sites More sharing options...
Rybags Posted January 26, 2006 Share Posted January 26, 2006 A broken trace or poorly seated POKEY chip? Quote Link to comment Share on other sites More sharing options...

Weird huh? 1006912[/snapback] Looks like you lost a trace. Did you lose the buttons 7 to Backspace? I attached a pic of the keyboard matrix.

Probably something on the MB. Edited January 26, 2006 by Almost Rice Quote Link to comment Share on other sites More sharing options...
+bf2k+ Posted January 27, 2006 Author Share Posted January 27, 2006 !!! I fixed it!!! It was a bad POKEY chip. Luckily I had another broken 800XL here for parts. The really good things are... not only is it socketed (so I can plug in a 32-1 OS that's been sitting here looking for a home for a few months now), but that parts 800xl machine I had laying around has the Real Good keyboard which was on some of the earlier machines. I used to have one back in 1984 that had that keyboard but I sold it and have never seen another one until now. It works fine on the newly repaired machine!! Thanks for all the input!
