Love this line:

  TC	BANKCALL	# TEMPORARY, I HOPE HOPE HOPE
  CADR	STOPRATE	# TEMPORARY, I HOPE HOPE HOPE
  TC	DOWNFLAG	# PERMIT X-AXIS OVERRIDE

I wonder if the Space Shuttle has a TODO left in there somewhere.

Other than gaining satisfaction from the historical importance of this code is there any conceivable way we can get some use of it - like try it out.

Even setting that aside, what is it I'm looking at? Assembly?

I'm pretty sure there is a website that simulates this computer 100%

I find it amazing that some revisions (e.g. KALMAN FILTER) are date stamped as July 14 1969.

Were critical routines being patched 2 days before launch?
