   If I'm not mistaken the microcode goes onto your TU58 boot tape that
goes into your 750's console, not onto the RA81.  The TU58 is the small
(and slllooowww) tape cartidge that makes a lot of noise when you turn
your 750 on from a cold start as it displays the messages on your
console device (usually a DECWriter III).  You should be able to use
'dd' to copy the files to the TU58...  on second thought, it might be
better to read the section in the BSD docs on "Installing and Operating
4.3BSD on the VAX" about making a console boot tape.  I've done this
before (over a year ago) on our old 730 which also uses a TU58 as its
console tape.  On second thought, if the 'tape' he is talking about is a
TU58 cartrige, you can use the console 'COPY' command to copy the new
files onto your boot tape (make sure to make a backup of it with COPY
first though!).
