Uppercase Greek shows the nepohualtzintzin, the Mesoamerican abacus. Made of maize seeds on horizontal wires, the seeds tumble back and forth toward the reckoning bar. It uses a vigesimal number system. The unit place marker is @.
Cyrillic uppercase results in the schoty, the Russian abacus. With ten beads per wire, it was widely used in Soviet Union shops until the 1970's. Letters ЛМНОП show the quarter ruble rod with only four beads.
Numbers 0-9 will produce the Japanese soroban, the most common abacus today. The vertical bar | is used to draw the edges, while # will mark the previous rod with a dot on the reckoning bar, marking the unit rod.
Uppercase Latin is the suanpan, the Chinese abacus. The extra beads give it some more computational power, especially in multiplication and division. Letters STUVWX show the suspended bead technique, which extends the suanpan even further.
