Anybody familiar with cutting the old style plaster?

Much more familiar than I wish...

Q1: Can I do it with a sawzall? If so what blade? Recall
this "plaster" looks more like flogging concrete.

You *can* -- but it's going to make a hell of a mess, and you're going to go
through a lot of blades. Not to mention shortening the lifespan of the tool,
if the dust gets into the bearings or motor (it's very abrasive).

Q2: If Q1 = yes, would an 8 amp sawzall likely be adequate?

Yes.

Q3: If Q1 = no, what should I use? Used a hammer/cold-chisel
on the kitchen and it was a SEVERE PITA!

Well, that's what I was going to suggest: hammer and chisel to go through the
plaster, then a sawzall to cut the metal lath.

I am now thinking maybe:

1.) Lay it out carefully with pen/marker (might be 9 sq. feet).
2.) Hammer drill with 1/4 or 5/16 " percussion bit every inch or less.
3.) Hammer and cold-chisel to detach "plaster".
4.) Recip saw to go thru steel mesh.

Is viable? I hate to knock huge jagged edges in the "plaster"
which does not break predictably with hammer/chisel.

Thanks,
