I have a few old rt hard disks (40 and 70 megs).  We no longer have rt's  
and I would like to use them for an IBM 386.  I think those disks are  
ESDI.  Is that so?  How can I use them on a 386?  How much would a  
controller cost?
Thanks, reply by e-mail

Three things..
  1) Your news software is mis-configured.  It produced a null or invalid
     "From:" line. It also was missing the Sender or Reply-to line.
     Had to guess your E-mail address by piecing 
     the news headers together.  Most likely your NNTP client host
     "piglet" is mis-configured.  Your NNTP server did not help much
     either..  With no valid "From:" line, some news software programs
     will drop your article on the floor.  
     Here is the news header as arrived at my site:

  2) No username was attached to the article, hard to figure out who
     you are.  No sig line was attached either..  I hope this
     E-mail address works that I cobbled together.
     I guessed with egrayver@piglet.caltech.edu.
     Just in case, I am posting this as well.

  3) Answer to your post..
     
     RT disks came in a varity of flavors.

     The R-40 disks are MFM and the same as PC-AT original hard drive.
     The R-70 drive is ESDI, as well as the E-70 drive. 
     The only difference is the number of sectors/track.

     Cost of PC controllers has been dropping, most likely around
     the $100.00-200.00 range, depending on features, speed and ect...
