They use an arm processor emulating the "Nut" processor in the HP-15C. Then using this emulation environment, they use the REAL HP-15C firmware so the calculator behaves EXACTLY like the real thing (except it runs faster) since the arm processor is clocked at 48Mhz. So it will not have any "Software" issues. The only issues possible are hardware implementation issues. Since they started with the credit card sized versions and sold them for many years, I would expect very few hardware issues either as they were worked out on the smaller models. I bought a DM-15L and love it. The most impressive feature is how quickly I can load/save programs
using the USB interface. When you can instantly load well written HP-15C programs from a huge library without the chore of manual keyboard entry, it makes a programmable calculator much more useful! I rarely change
the program(s) in my HP-15C Limited Edition, but I have already loaded dozens of programs into my DM-15L since it arrived two weeks ago.
