 Someone is trying to boot Fortran off of the Disk on an IBM 1620 me thinks  
 Isn't 00796 where all-well-behaved programs went to die? I.e. reload 
 Monitor (sort of a CALL EXIT)?

We have a winner.  
Just to add to the trivia, to boot the disk you needed a few more characters:
3400032007013600032007024902402111963611300102
Which if you were on a model 2, you needed to make sure that indirect
addressing was turned on (nothing worked right if you didn't!).

After doing that a few times, you remembered it pretty well. (Stuff deleted)

So Tom,

Do I at least get partial credit for knowing it was from the IBM1620?  A 
friend of mine told me that sequence 30 years ago - and along the way I got 
confused as to the function. (I know - excuses excuses ;-)   I can 't explain 
why I'm carrying around that data in my head either... I only programmed in 
GoTran twice, i.e. hands-on a 1620 that many times back in the 1970's at Oxy  
College in Pasadena on the weekends. A high school buddy was the true Guru in 
1620 Machine language.  As for the IBM1130 - I've only programmed on one of 
those in Fortran IV once (though my college buddy Bob seems to have one he is 
trying to ressurect  - http://www.dvq.com/1130/1130.htm)
