Hm weird, since going by the file sizes, the L file is the larger one,
and not bootable.

 11M  BB-J0830-01.M01_RSX11M+_V4.6_1999.tap     <-- booted off this one         
 30M  BB-J0830-01.L01_RSX11M+_V4.6_BRU_1999.tap <-- contains the string         
      ***THIS VOLUME DOES NOT CONTAIN A HARDWARE BOOTABLE SYSTEM ***            
      near the start

I actually tried booting it once, and it then prints the string.

Seemingly that is still true with these files despite different names.
Of course the pdf I have is for installing 4.3 and calls the boot tape
BRUSYS.

I wonder why the M tape is so large; applying "strings" to it shows lots
of stuff including Macro-11 source files.

Could it still be, like that manual suggests in section 2.2.1 on page
2-5, that it is indeed "BRUSYS Standalone Copy System and Layered
Product Corrections"?

Oh, still haven't had much time to look at Kermit :(
