15C LE -- fun with the PSE - Katie Wasserman - 09-14-2011

The PSE bug results in some interesting displays, try this little program:

LBL A
PSE
SF 9
RTN

and run it.

or this:

LBL A
PSE
PSE
SF 9
RTN

and run the with a number greater than 1000.

Annunciators blink too. Try it with RAD and USER modes enabled.

Curious!

Running on the HP15CLE, the display alternates between 'running' and the number in X. With the double-pause code only the 'USER' or GRAD or RAD annunciators blink.

Single Pause code:
Running on an original 15C, the display is blinking. Of course, clearing flag 9 stops this blinking - returning to a normal display.

Running on the 15C2010HHC (with code received there), the display totally blanks; but briefly reappears when a key is hit. Again, clearing flag 9 returns the display to normal.

Sounds like we need to avoid PSE with the new 15c. LOL

... and the radix mark and the thousands separators.

The display driver in the original r2d2 disables the annunciators
when it is in blink mode. So that needs to be explicitly addressed
in an emulation scenario.
