  Wow, so that goes without the cptape program. The

 one-liner sed command to convert the log file in a series of dd

  No, I used cptape to get the files off the original, just a really
crufty script to put 'em back.  And I have a brand new sed & awk
O'Reilly text sitting in the den.
  Of course, that doesn't fix your broken source
tape. 
  I dunno if the source tape is broken.  I don't have any verified good
eqipment to test with it...  I think the SCSI TK50 was the problem.  I
do know that I have a problem with the RQDX3 board, or the distribution
board, or a cable.  The fact that the MFM formatter was hanging led me
to think the Diags were busted, but further testing with both tapes says
that the RQDXA is failing.  Bah!
