Actually, it would be good to check 2 things:
- ? characters set contains PI = later, corrected, M102/M200 character set
- ? ROM does not contain trig fault = later, corrected, M102/M200 character set
- note the serial number
With these data, we can determine if both corrections - the newer character set
and the elimination of the trig fault - occurred at the same time. If not, we
shouild (theoretically) bump into machines that don't have the trig fault but
do have the newer character set, or vice-versa. So far, but by only one example
(my machine), we know that both corrections appear together.
One thing I should check is, if my machine was modified in any way with a new
ROM. But for that, I have to find it (hard) and open it. (even harder) :-/
Anyway, the check can be done using the PI.BA program listed here, below or in
my file section on the website.

Hello Peter:
CHR$(136) is what you seek.
Rather than perform PRINTCHR$(136) on several laptops in order to see if the
lower case Greek letter Pi emerges, two pages within the NATIVE manual show all
of the character shapes: page 18 for the M100 laptop, and page 19 for the M102
and M200 laptops.
The NATIVE manual file (as well as every file of NATIVE) is available for
inload at the Club100 Member Upload Library. Follow the path Club100 Member
Upload Library/Ron Wiesen/NATIVE/Native.pdf.
See page 18 which shows all of the character shapes of the M100 laptop.
Character code 136 [i.e., CHR$(136)] produces the character shape of a ! symbol
that's been rotated 180 degrees.
See page 19 which shows all of the character shapes of the M102 and M200
laptops. Character code 136 [i.e., CHR$(136)] produces the character shape of
the lower case Greek letter Pi.

Great, remind me of what CHR$() I shoiuld check, I will be glad to
chime in with the info and serial number of my unit.
