I wonder whether it's a just question of kernel config. 
Anyway, along with the release of 1.5, the web page for 
platform independent support for TC boards had been updated
to include the PMAZ-A.

Well, a /300 supplies only two usable drive bays, and I can't
make the bus too long. I also don't expect to be able to obtain
one of the successor models, supply is limited ;-).

>[...]  If PMAZ-A can not run with DEC3000, that must be fixed.
I would appreciate that.

>I have no PMAD then am unable to fix the issue.
Maybe someone else can report a working PMAD in a /300 (or L, X, LX) 
or even another DEC3000? Just in case it depends on firmware or
board revision, or me being too stupid.
