I know it doesn’t have anything to do with HP calculators, but I just uploaded my Texas Instruments TI-95 Emulator for Windows 9x/NT/2000/XP to http://hrastprogrammer.tripod.com/TI95E/TI95E.ZIP. Installation instructions haven’t been provided because the archive contains only one file (TI95E.EXE) containing the emulator. It is free for non-commercial use so no one can say that I don’t give anything for free :-)
As this is a true emulator emulating TMS70C46 CPU, you’ll need ROM listings from http://www.rskey.org/ti95rom.htm - just download them and store all files into the same directory where TI95E.EXE has been stored and run the emulator.
I am looking for the ROM dump of Mathematics, Statistics and Chemical Engineering modules so I can load them into the emulator. Furthermore, with the appropriate ROM, I can emulate TI-74 BASIC calculator, as well (because they share the same design). But, I currently don’t have this ROM so if anyone would like to dump and send it to me ...
Best regards.
