TI-57 Emulator for HP-48S/SX/G/G+/GX, HP-49G and HP-49G+ is finished Message #1 Posted by HrastProgrammer on 15 Jan 2006, 1:50 a.m. 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.
