   Depending on the specific model, the "console" port is either serial 1 or serial 3. Umm, wait - VAX 2000? - you aren't talking about the "lunchbox" VAX are you, perchance?"

   Not rare at all. The H8571-J MMJ to DB9 adapter is still an orderable part. The "new" versions aren't as sturdy, though - as they are "clamshell" construction, rather than molded.

   If you make up your own "DECconnect" cable, be absolutely certain that you put the locking tabs to the same side of the cable (I always put them to the "rib" side). The signal lines are .not. symmetrical, so flipping one connector doesn't make it a "null-modem" cable - it makes it utterly useless.
