This project is a good exercise for learning Logisim Evolution and evaluating its capacities.
It's very easy to use, it's quite capable and delivers when I ask a lot.
The Magic-1 computer from Bill Buzbee is an excellent candidate for evaluating Logisim and see if it can simulate a homemade computer.
Note: use the logi7400ic.circ file from my github project, not the original one (link provided) since it won't work with the current version of logisim.
