Where to get HP65 schematics?

But I can't find anything on the card reader.

I have already tried to contact Dave Colver for the schematics CD but unfortunately did not get a response.

Any ideas are much appreciated.

Have you looked at HP Journal for May, 1974, volume 25 #9? That whole issue is devoted to the 65. It is on the Museum DVD or at hparchive.com.
