Okay, I downlaoded 'romdump2.zip' and I extracted everything. Then I sent the rom86.86p to my calc and ran the romdump.exe. Then I ran the ROM86 program on my calc and tryed to send, (I guess) the ROM image to my PC. But nothing seemed to happen, what should I do. Please give me as detailed a description as you can. I would really appreciate it. Thanks. Patrick
