Z80 Assembly Coders (Z80AC) was an active assembly programming group for the TI-8x graphing calculators.
Although they had several interesting projects under development, most of them were never released to the public. Some of their best releases include a TI-83 Disassembler, BugOS, The Genetic Code, and Stunt Copter. Doug Torrance also wrote a few assembly programming tutorials while a member of the group.

The Z80 Assembly Coders were formed back in July of 1998 with 2 original members: Will Dempster and Tim Buckingham. Z80 AC was formed when their two coding groups: Omegasoft and Phrozen Fire, joined up in a merger to create better games and utilities for Z80 based calculators. The coding group went 'public' in a September news article on ticalc.org. On January First of 1999, the first overhaul of Z80 AC was completed, rooting out several old and inactive members, in hopes to save the organization. After a few weeks of work, the group slowly began to vegetate once again. In April of 1999, Alex Liemen and Jimmy Conner were added to the staff in an attempt to revive us once again.
This time, our site became more active with another site overhaul and several new programs. In July of 1999, Will and Alex, now the President and Executive Vice President, decided that Z80 AC should go into 'hibernation' until y2k, when a barrage of new programs and a php3 enabled website could be created. In that period of time, Tim Buckingham, a Co-President and Co-Founder, resigned for personal reasons. On January 1st, 2000, Z80 AC ushered in a new era of programming for TI-Calculators by releasing a variety of new software and games for TI-Calculators and other computer platforms. This should begin a long an prosperous future for Z80 AC.
Z80 AC has an IRC channel on EfNET. Our channel name is #z80asm or #zed80asm in the case of a takeover. There you can find many of our members to talk to. Some of us that commonly go online are: Will (RavenMoss), Alex (Milagro) or Jimmy (Cigamit). You can talk to us about anything you want regarding programming or otherwise. Just don't bug us or you will be ignored :P. No really, we want a high level of discussion in our channel so if you want to be degrading about things that we have done that are stupid (um… no comment :P) then take it elsewhere like #ti-files.
