This one times out on my ccd every so often. Even worse, the machine will
not come back to normal operation. Even more worse, it handles write access
to my HP DAT much worse, i.e. times out and halts the system, than the ncr
in my old board (which burnt down last week due to fan failure).

So, who is going to import it?
I have trouble buying an NCR controller, because al resellers say it didn't
pass the CE-regulation.
