I was getting the exact same error on a 3/50 a couple years ago.
Except that time, I was trying to boot SunOS 4.1.1 from a tape.  I
never figured out what the problem was for sure, but it could have
been a bad tape, a bad tape drive, or maybe a malfunctioning 3/50.

Maybe the FE's manual has a list of exceptions for the sun 3
hardware...
