   What's old is new again.  ;-)  Even IBM are bringing back
liquid-cooling.  For an eye-opening read, try the DECsystem-10
Techincal Summary from 1980.  Tens had stuff VAXen never even

   VMS is pretty cool, but the VAX iron suffered very badly from
microcode-induced bloat.  One word:  "poly".

   Your VAXstation will probably  outperform the machines listed
above.  Even a little VAXstation 2000 is 90% of the power of a
11/780 (without the wonderful pdp11-compatibility bits, though).
The 11/730 makes for a nice, but pokey, home computer.
