Otaku Programming Association (OPA) was a programming group for the TI-83+ graphing calculator. They released a few notable programs including a modified version of Falldown called Fallup and Latin Translator II for the 89; both programs were featured on ticalc.org. Hieu-Trung Le also wrote a TI-Basic programming tutorial for the TI-83 and TI-83+.

The word "otaku" means fan in Japanese, and is commonly used to refer to anime and manga.

Group History

(Taken from Radical Software about page)

InterCalc.org was the by-product of the Otaku Programming Association, founded by InterCalc.org's Vice-President Chris Rojewski (gro.tfoslacidar|sirhc#gro.tfoslacidar|sirhc), which was renamed from Abacus Software, Inc. (ASI), founded Christmas 98, later called AbacusĀ². It was renamed to OPA on December 6, 1999. Joshua Vanderburg joined later became the president around Febuary 2000. With Chris leaving OPA, this led to a few more members leaving and OPA wasn't making many programs. In March of 2000, Joshua decided for a change. He bought a domain name, purchase some server space, and set up InterCalc.org with the help of Brandon W. Chris was to re-unite with Joshua in June of 2000, Joining InterCalc.org. Many members tried many times, but InterCalc.org would never be announced on "the ticalc.org project" (ticalc.org), and even with the announcing on Dimension TI, InterCalc.org never received more than an average of 25 impressions a day. In September 2000, InterCalc.org received an makeover, with a new site design, server, and the first useful message board for the entire TI community. TI-Galaxy (ti-galaxy.org) had one, but it wasn't of a high enough quality to be used by all. In October 2000, Joshua planned the redesign of InterCalc.org with the help of Brandon W. On a spur-the-moment occasion, Joshua asked Michael Vincent to combine his site of Radical Software, he agreed and Radical Software exists as you know it today.

March 2000 - We have a short "war" with Novasoft, who at the end of it all go and join the OPA.

February 2000 - OPA accuse us of hacking into their site - fortunately it turns out to be someone else :)

Miscellaneous

OPA was one of the sites that got hosting through ticalc.org.
