I thought in the Netherlands we use the standard MSX (international)
keyboard. Maybe the interface is made for a non-standard MSX keyboard ?
There are Dutch PC keyboards but they are very hideous to use. They have a
Alt-Gr button and have rearranged some ;'/<>? keys. But PC keyboards send
scancodes based on the position of the key, and is then remapped in
software. So if you want your " to be at the place it is on the keyboard,
you will need to map it to another key.
But I bet you can type blind, right? Then there is no problem if you are
used to a standard US keyboard.
So it works like this (I think):
1. You hit a key (for example: P)
2. PC keyboard sends a code to interface (position of P)
3. Interface translates this according to a map for a specific PC keyboard
4. Interface simulates a 'hit' on the MSX keyboard, according to a map for a
specific MSX keyboard
5. MSX interprets this 'hit' according to a map for a specific keyboard (the
one it came with)
