Today, I discover about "Human Resource Machine",  (https://tomorrowcorporation.com/humanresourcemachine) by  https://github.com/adumont/hrm-cpu, https://github.com/nrkn/hrm-cpu and https://spectrum.ieee.org/three-computer-games-that-make-assembly-language-fun.

The hrm-cpu is a "human" sequential machine, with restrict set of instructions, very like as Jelly's ones.

The HRM literal jumps behave as BF loops \[ and \] and  the HRM literal bumps behave as BF  \+ and \-.  Add and Sub are trivial.

Jelly can process as a 8-bit HRM, using ten or more i/o tape cells as internal storage and few macros.
