TI-57 Emulator for HP-48S/SX/G/G+/GX, HP-49G and HP-49G+ is finished



#2

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.

Hi Namir and Peter,

There are 3 ZIP files (one for HP-48S/SX/G/G+/GX, one for HP-49G and one for HP-49G+), each about 12K in size. Can I send them to you by mail?
