It looks the same at my hand. PMAGB-B has reportedly many variants.
Old Mach source code says;
* I am confused here by the documentation. One document
* sez there are three boards:
* "PMAGB-BA" can do 1280x1024 @66Hz or @72Hz
* "PMAGB-BC" can do 1024x864 @60Hz or 1280x1024 @72Hz
* "PMAGB-BE" can do 1024x768 @72Hz or 1280x1024 @72Hz
* Another document sez things differently:
* "PMAGB-BB" can do 1024x768 @72Hz
* "PMAGB-BD" can do 1024x864 @60Hz or 1280x1024 @72Hz
* I would be inclined to believe the first one, which came
* with an actual piece of hardware attached (a PMAGB-BA).
* But I could swear I got a first board (which blew up
* instantly) and it was calling itself PMAGB-BB...
* Since I have not seen any other hardware I will make
* this code as hypothetical as I can. Should work :-))

It should not make matter for NetBSD/pmax. All of parameters can
retrieved from the TURBOchannel device, and video driver distinguishs

I think I have. I will go back to a storage and look for the one
which should be got rid of 2 years ago.
