Abacus

An abacus is a counting tool that may be used to perform simple arithmetic and is useful for an adventurer to quickly gain an overview of their finances. Such devices appear in Ultima VII, Ultima VII Part Two and Ultima VIII.

Description
An abacus consists of a wooden frame, which houses several rows of beads on wires or polls. The abacist may use these beads (which represent certain decimal or hexadecimal values) to perform computations and may therefore make a quick tally of goods and money. Using abaci in Ultima VII will calculate the sum total of gold coins carried by the party. In Ultima VII Part Two, the use of an abacus will reveal the amount of Monetari, Filari, Guilders, gold bars, gold nuggets, gems, and jewelry the group is carrying. In Ultima VIII, an abacus may only tally obsidian chits and only when they have already been gathered into a single pile.

Trivia

 * Iolo begins Ultima VII with an abacus and will offer to explain its function to the Avatar when asked.
 * In Ultima VII Part Two, abaci may be purchased from Bucia at the Capessi Canton Moonshade. One may also be found in the palace of Fawn some time earlier.
 * In Ultima VIII, an abacus may be found in the home of Mythran the sage. However, due to the stated limitations above, it's pretty useless.
 * In Ultima IV an abacus is used by the Gypsy in the character creation process.
