I guess there's a reason you want to push these films well beyond their
capabilities?  The massive film/dev chart on my Web page indicates that Xtol can
be used at 20C for 10.5 minutes to push TMX to EI 800.  I think you'll pretty
much trash any shadow detail doing this, but perhaps this is what you're trying
to do.

I can't help with the Konica, as I expose it EI 8.
