Almost.  The PMAG-BA is the cfb (dumb card) and the PMAGB-BA is the sfb
(relatively smart card).  The programming info for the sfb is patchy at
best (AFAIK), but it basically works as a cfb if you don't use any of
the "features".

I've still got a /260 and a PMAGB-BA that will one day never see Ultrix
again...
