 Please be aware however that you may have troubles using the dual-SCSI 
(PMAZB-AA and PMAZC-AA) options in a VAXstation due to the limited 
external slot clearance.  A standard HD50 SCSI plug will simply not fit 
into the opening of the mounting frame used with the DWCTX-BX adapter to 
attach a TC option to the system's enclosure.  It's a pity DEC didn't 
choose to use VHDCI connectors instead; perhaps it was too early for them.

 Hmm, the 3100 does not have TURBOchannel though, you'd need one of the 
5000 boxes.
