AFAIK, this is the first time ever that TI machine code can be executed on a HP CPU :-)
This famous vintage calculators is fully emulated because the emulator is based on the real ROM (object code retyped and analyzed by me from the original TI patents).
Features:
(*) Continuous Memory - data and program memory is preserved after exiting the emulator.
(*) Light-sleep mode when waiting for a key is implemented.
(*) Auto power-off is implemented.
(*) Ability to save/save RAM to/from a RM57 variable.
(*) Emulator is much faster than real calculator.
(*) Pause duration is lowered to about 1/2 second.
(*) Advanced LRN functionality: Current instruction is displayed in text form above the regular display in LRN mode.
The first three features in fact turn TI-57E into never released TI-57C calculator.
I won't release TI-57E for Windows because my primary concern are HP-48 and HP-49 calculators. For this reason, I gave the ROM and the emulation code to Eric so he can include TI-57 into Nonpareil as stated in another thread (this code is written in Delphi Pascal so he must translate it into C).
TI-57E is freeware. I uploaded it to http://www.hpcalc.org some ten days ago but it still didn't show and isn't available for download. I don't know the reason for this. Maybe you can suggest me another location for the upload ...
Best regards.
