The Programmers Group was a programming group for the TI-83+, TI-86, and TI-89 graphing calculators. The group had several notable program releases and several projects under development, including XLink, Hearts, LitesOut, and RPG. The group was created out of the inactivity of the Otaku Programming Association (OPA) programming group, which itself was created from the Abacus Software, Inc. programming group. Intercalc later merged with Radical Software, and all of the members and content were then transferred.

CalcWire merged into InterCalc in September 2000 when Casey Woo decided to shutdown CalcWire due to his loss of interest in graphing calculators. Subsequently, InterCalc inherited some of its members and their programs, and the Calc Exchange and TopTI services. Jason George had his own programming group, The Programmers Group (TPG), while part of Intercalc. Sebastian Reichelt was helping with the TIGCC C compiler for the TI-89/92.

Group History

(Taken from the Radical Software about page)

Radical Software is the result of a programming group merger in October of 2000, comprised of two groups, Radical Software and The groups were combined on the following basis: was to acquire the Radical Software name, members and programs. The founder of Radical Software, Michael Vincent, was to be one of the two Sr. Vice Presidents. The web programming aspect of the site was to be done by Joshua Vanderburg, Michael Vincent and Brandon W. Joshua Vanderburg pays for the web host. The rest follows its own course.

Radical Software was founded by Michael Vincent (gro.tfoslacidar|leahcim#gro.tfoslacidar|leahcim) in the fall of 1998, and was hosted by Dimension-TI ( at starting in August 2000. At the time of the merger, there were five members, one of which also belonged to The Radical Software archives contained about 47 files for five calculators in eight different languages. The site wasn't updated enough to bring a whole lot of viewers, but brought in about fifty individual IPs a week. A contribution to the few impressions were the mass of programming groups already in production. Programs were coming, though. En mass… was the by-product of the Otaku Programming Association, founded by's Vice-President Chris Rojewski (gro.tfoslacidar|sirhc#gro.tfoslacidar|sirhc), which was renamed from Abacus Software, Inc., 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 with the help of Brandon W. Chris was to re-unite with Joshua in June of 2000, Joining Many members tried many times, but would never be announced on "the project" (, and even with the announcing on Dimension TI, never received more than an average of 25 impressions a day. In September 2000, received an makeover, with a new site design, server, and the first useful message board for the entire TI community. TI-Galaxy ( had one, but it wasn't of a high enough quality to be used by all. In October 2000, Joshua planned the redesign of 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.

This site was originally coded by Michael Vincent, with the exception of the behind-the-scenes PHP news script for the front page. Brandon Wilson re-designed it in October of 2004 and has been thoroughly tested in Internet Explorer 6. It should work in other browsers as well.

Members, TopTI, Calc Exchange…

Well, after much consideration, Casey Woo of CalcWire has decided to shut down CalcWire, due to his loss for graphing calculator interest, and to his loss for spare time. Due to this will pick up a few things: The remaining members of CalcWire who would want to be part of, their programs, Calc Exchange, and TopTI Sites. Casey will become a member of for the sole purpose of administering the TopTI Sites. We are redisigning the TopTi Site code with the help of Casey Woo, so it may take a while to have up. Calc Exchange will be fairly simple and should be up in a week or so. The remaining members of CalcWire will come as they see fit and no programs will be added of a CalcWire member who does not join We hope this is not the beginning a "calc-site" trend…
