I am in the process of relocation to Europe. THe power choices are Euro 240 single phase or 380 three phase. Can the 770 be supplied to work with these power types?

I believe I talked to you on the phone last week just wondering if youve made a decision yet? And any interesting findings you have made?

The 1100 runs on 240 v

I believe Europe is mostly 240VAC, 50Hz (there may be a 60 Hz country or two as well). 50 Hz needs more iron in transformer cores, and the Tormach does have a couple- as well as contactors, where the coil/core amounts to the same thing. Tormach -like many electronics these days- converts mains power to DC, then supplies the works with whatever it needs. Thus it's mostly a question of whether the front-end stuff is OK on mains power. I've never asked, but I suspect that the Tormach design philosophy was to be world-compatible as far as possible.
I'd check with Tormach to be sure you don't need to change out a component or a fuse or two in a current machine, or order a machine specifically for Euro mains power. Why guess when Tormach will undoubtedly give you a straight answer and set you up with any changes you need?
The 1100 works just fine in Europe without any modifications. The 770 only comes as 115 vlot, so the poster will need a transformer. My ballpark guess would be 300 or 500 EURs.

Even cheaper:
3000VA 3kVA Step-Down Transformer, UK 240V to US 115V, CM3000AUS | eBay
Looks like a no brainer.

PS: I'm not saying that the linked transformer is the correct one to use, but it puts you in the ballpark with respect to price.
One comment about stepdown (or up) transformers for voltage conversion. Some are autotransformers; that is, they are a tapped coil rather than two isolated windings. This is a clever electrical trick that saves money (and is commonly encountered in the lab with the Variac transformer). The arrangement can be dangerous since it can result in full line voltage at the output in some failure modes. Works just fine; but be aware that you're not dealing with the usual isolated windings and that you might be taking on an unanticipated risk. Easy way to tell (if the label doesn't): continuity check. The autotransformer will have all leads showing low resistance in any combination, whereas isolated windings will show no continuity between at least some sets of leads.
