Sorry to be a pain, but I have hunted high & low for the answer to this one: Been a while since I had the cover off a 1200 & in installing a 2.5" hard drive in a newly-acquired A1200, I appear to have succeeded in mis-seating the keyboard ribbon cable.
I have reopened the case and double checked that the cable is now qaccurately installed, but sadly I now have no response from the keyboard on the QWERTYUIOP{} keys - all the others work OK so it looks like I zapped either an address line on the keyboard itself or on the keyboard chip.
Since I no longer even remember which chip controls the keyboard, any slightly more expert advice would be greatly appreciated, including any possible sources of keyboard chips if that is what I fried. *sigh*
Thanks in anticipation Ivan
