Also: 6809 has PSH and PUL that take a register list. ARM's LDM/STM is a direct copy of this feature (via 68000's MOVEM). Other RISC processors did not have a list.

The conditional branch instructions (and set of flags) for all of these are from the PDP-11.

Off topic -- thanks for your work writing and maintaining JOE. (Assuming you are that same jhallen.) Been my primary editor for about 20 years now.
