I'm not sure if we ever had a ti-specific z80 compiler like tigcc was for 68k-based models, maybe check on http://www.ticalc.org/ François. ^ permalink raw reply [flat|nested] 3+ messages in thread

At one point there was a community and quite a few games for it :). The issue with emulating it is that you need a proprietary ROM that can't be redistributed. I think the same goes for the other TI graphing calculators. Stefan ^ permalink raw reply [flat|nested] 3+ messages in thread

OTH they did send a DMCA letter to those who breached their signing process to make their own flash app. François. ^ permalink raw reply [flat|nested] 3+ messages in thread
