I'm pretty sure it's keytronic, but there's a chance it's hall effect. I'll have to pull my wangs out of the closet and check if you want to know for sure.
Sadly, both keytronic and hall effect keyboard can come with bent in the front spacebars (and very similar keycaps on top) so it's hard to visually distinguish them.
edit: keytronic almost for sure. the reset key has a very strong spring under it.
I thought it was quite nice for a vintage foam and foil. Very smooth.
