We no longer support Perch 1, so we don't have an up to date CKEditor for it. In theory there should be nothing stopping you installing CKEditor in Perch 1 - the process is much the same as doing so for Perch 2.
I tried with one of the recent versions of CKEditor but it doesn't work with Perch 1, nothing shows up. I see from the change log that for version 1.6 it was "Updated for Perch 2" so I don't know whether that made it stop working for P1.

I didn't mean our CKEditor package - I meant building your own from a raw CKEditor download.
If not, then the answer is probably no. Perch 1 is very old at this point.
