Re: DC IDE adapter questions

First, there is no warranty on any information about these hardware.
Unlike software, no one can help to debug hardware from remote end.
Unlike software, building hardware often requires much more money,
but pay it at YOUR OWN RISK.
Furthermore, these hardware design might be a bit fragile and
it could be unstable.

I'm using Kiyoshi Ikehara's DCEXT. I also have a patch for NetBSD 5.0.

Probably you need to read "Realted-links" on that page.

I don't think there is such connector.

In which schematics?

In general, such "experimental" schematics are written for people
who can assume what they are and who can debug it themselves...

Using correct parts doesn't mean it should just work.
Actually I had to fix several connections to make DCEXT board work.
