Gene, not sure, if Bru was available in 1989, when this backup was made.
It appears not being compressed, as the raw disk dump shows plain text, like this:

OSTerm V2.0.8 (C) 1989 by Vaughn Cato Copying permitted for non-profit use only To furthur the development of superior software, please contribute $10.00 to the author at: 1244 E. Piedmont Rd. NE. Marietta, Ga. 30062 Special thanks to Phil Zeigler, who thought when I could think no longer.
