Well, technically, I would say it isn't. BTW, I have an old 1.2 rom, and I have a new ti-86 now with a version 1.6 (I think) ROM which I am having trouble dumping. No program will let me do it. I got close with romdump8x, but it made the file size for the ti-85. I have a TI-GraphLink and several dump programs..any suggestions?
