Bob,

Two for two.  This will also be in 3.8-1.

The bug is actually a side effect of not implementing 7-track tape 
support conservatively.  Before "Pierce format support," all tapes were 
in SimH format, and the conversion tools pretty much guaranteed clean 6b 
characters.  The Pierce format support does not.

Cousin-bugs may exist in other 7-track tape simulators (such as the IBM 
7094); I will check.
