I should point out that those headers aren't
suited for plugging
directly into an IDE drive; the power and ground pins land on
some meaningful data pins. You need to make an adaptor. Also,
avoid using 80-conductor cables with those connectors; those
cables internally bus the IDE grounds together, which don't
correspond to the grounds on the board. You won't short
power to ground or anything like that, but you will lose a few
otherwise useful pins.
A quick glance at the DE0 schematic just shows direct connections
to the headers.
On the bright side, the DE0 and DE1 use the same
pinouts for
those connectors, so things should be cross-compatible. The
DE0 even runs some clock pins out there, which can be
pretty useful.
I made a quick choice with the DE0 hoping it would have all what I need.
That was a bad choice on my part, from just reading the web site.
The docs are there, but you have dig for them.

None the less, both boards do make nice hardware for the classic machines.
