I was successful to run TCWSCONS kernel on DEC3000/300
with cfb (PMAG-B = CX) TC option card attached.  I had no
problem to compile a new kernel. What's wrong in yours?

I have no idea for PX(G).  One of my concern is TC slot numbering
scheme differs between model 300 and [456789]00.  But you had a
compile problem, didn't you?

Since I could not bear CX's low refresh rate (60Hz) and poor video
rendering (Alpha processor performs quite badly for sub-word bit
manipulation), I prefer 300 built-in video (HX equivallent) over it.
