Hi! Interesting question. This calculator has only 146 kB RAM and only 256 kB of the ROM is reprogrammable flash. Also, the display has very low resolution. You might be able to get some workable solution by starting from Rayer's ROM OS approach, but everything is very small in that calculator. So you probably have to be really experienced to get it to work. And you have very little space to add interesting files to work with, too. http://www.rayer.g6.cz/romos/romose.htm
My guess is that the calculator does not have IBM-PC-compatible hardware or even an IBM-PC-compatible BIOS (even RayeR's ROMOS assumes there is such a thing). This will likely be one of the main problems in getting something like FreeDOS to work on the device. Certainly the calculator's CPU may be compatible with that used on machines that run DOS. But the rest of the hardware --- including the key input, screen output, and even serial communications (?) --- seems very different indeed. Meantime, without knowing more about its internal workings, it is hard for me to say more.
