Easiest groups/lineages of machines to port software between?

[Paul Dale]

The 34C would go to the 15C in a straightforward manner. What about the 25 to the 33E or 33C?

The 34S was designed to just about run 42S (and hence 41C) programs as is. It isn't quite there but it is close. We changed the bitwise operations (for the better I think) which broke easy compatibility with the 16C. It should also run 34C, 11C programs as is and 15C programs that avoid some matrix operations.
