Hi,
Try Sky View Café at

which, for 1 January 1000 AD, gives the declination of Polaris as 83d 47m 43s.
If you wish, you can go back as far as -6000 when the declination of Polaris was 50d.

Alas, it looks like it doesn't change back that far. It still has Polaris
at around 89 degrees declination. In 1000 AD I'm pretty sure it's
something like 6 degrees off that.
