Yea, I posted it last week.  Grab the sebhc.0405 file from the archives, or 
get the H8-5 manual.  But if you are emulating the serial I/O to the tape, 
the format will probably be transparent anyway since PAM takes care of it 
for you.

I believe what I listed above is the complete set.  If  you add all those 
you should have every possible code covered.

I'm surprised it worked at all.  040.000 is where PAM's ram scratchpad is.  
Tape software starts at 040.100!
