> who mentioned a key repeat problem (wrong key being duplicated)?

It's me... I checked at home and the problem is present under AmigaOS
too... This might be a hardware issue.

my machine: A1200 (Commodore), internal keyboard. (stock A1200)

When you type `ls' with keeping `l' pressed, you get `ll' instead of
what you get on my PC for example: `ls'. This is quite annoying, but I
don't know if this can be circumvented by software. I don't have
either the documentation nor the Amiga here, so I can't test...
