OT: Beta testers for the dark side of the universe Message #1 Posted by Joerg Woerner on 27 Jan 2013, 12:03 p.m. A friend of mine developed a Simulator for the TMC0501 based TI calculators (SR-50...TI-59) and is looking for a few beta testers. Interested? I played with it multiple times during the development phase and it is unbelievable accurate! Calculator forensics is precise to the last digits and even knows the differences between the TI-58 and TI-58C. Can't wait to see the SR-60! Regards, Joerg

Re: OT: Beta testers for the dark side of the universe Message #5 Posted by Eric Smith on 28 Jan 2013, 3:33 a.m., in response to message #2 by Marcus von Cube, Germany Unfortunately, the chips in the TI-88 have essentially no similarity to the TMC0501. It is also not at all clear how to read the ROMs of the three custom-designed microcontrollers. It is reasonably likely that the microcontrollers have a test mode, but what little information that is publicly available doesn't describe it. If I could buy a non-working TI-88, I'd decap and photomicrograph the chips for reverse-engineering.

The listing of the patent is barely readable, could it be possible to get a dump of the rom of the TI ?
