Title: A1200 keyboard problem
Post by: btrpathead on March 07, 2004, 02:32:06 PM

Hi.  At a car boot sale today I picked up a A1200 (my first Amiga ever!).  It does seem to have a problem with the keyboard.  Whenever I press "L" I get "L`", when I press "9" I get "9-" and pressing "4" on the keypad presses 4 and return!  The only way I was able to test this was with the shell program i the workbench 3.0 disk I got with it.

I also get Exile with it and that seems to play fine.

Hmm, strange. Never come across that before!
I guess the 1200 could have been kept in a damp place for a while messing up some contacts in the keyboard. Try to get hold of another 1200 (one being sold for spares for instance) and swap the keyboards.

You could also try reseating the keyboard ribbon. It may have come loose.

I have a few spare a1200 keyboards which are working fine,

Hmm, sounds like a Keymap problem to me.
Do you have the "Workbench: Tools 3.0" disk also?
There is a tool called Input in the Prefs dir.
Start it and select a different Keymap that fits to your locale. Maybe the keymap is not a standart Workbench one, like some cracker groups, game developers, intro/demo coders create for themselves to give access to many keypresses at once just by a single keypress. In this case you can delete it.
If you want to see what keymap is in use, then start this Input tool and look at which keymap is selected.
Then insert your Workbench System disk and delete the keymap from your Devs/Keymaps dir.

I hope that helps. :-)

No.  I only geo 3 disks with it, Workbench 3.0 and Exile disk 1 and 2.  At one point when I had it open pressing space would give ". " and pressing 9 would give "9-=".  I also forgot to mention that the reverse is also true, pressing - would give 9- and pressing [ would give o[ etc...

Anyway as I had it open I accidentally gave it quite a sharp knock and the keyboard went back to the previous state.

EDIT:

I have opened up the keyboard and it seems fine and the connecting ribbon also.  Back to the original problem, I forgot to mention that if for example I press and hold 9, I would get "9---------" and I get exactly the same if I press -.  The same is tru for the other keys I mentioned earlier.
