SR-56C? Interesting idea.

Thanks for the explanation.

In the TI-57, the display goes black when doing an "expensive" computation such as "88 sin" which takes a couple of seconds: in order not to be even slower, there is no refresh of the display.

Until I understood what was going on, I was puzzled why the display of the emulator would never go blank. At the end, to match the behavior of the actual device, I had to explicitly set the display to blank if it hadn't been updated in the last x ms (I think I ended up using 250 for x).
