In the course of testing a fix to my HP97 emulator, I ran across an interesting glitch on the real HP97. Maybe someone out there can verify it.
1. Calculate N! using 70 - creates display overflow.
2. With Print mode in TRACE - Press SCI
This displays on printer:
"9.999999999 99 ***"
FIX displays the same as above.
3. Now, Press ENG
This format prints
" 9.999999999+9 ***Actually the last 9 has a glitch - looks like a badly shaped 7
printed over it
Can anyone confirm?
Thanks,
Mike
