I just re-read the article on Padial's keyboard interface (will be
published in MCCW 92) and guess what... There is a special connector from
the cartridge to the turbo R's main board! So although the cartridge is
still inserted in a slot, some signal is travelling another route.

I do have a turbo R, but not a cartridge that uses any MSX-interal I/O
range.

I am beginning to believe you, but I'm not fully convinced yet.
Can anyone tell me what happens when you insert Padial's keyboard interface
in a turbo R and don't connect the extra link to the main board?
