Found my Model 100 back.
//Strange, that I as a collector, have several Models 102 and 200, but only one
Model 100//
Checked again:
- it doesn't have the trig error
- it does have the Pi character
But it also has a "repaired" sticker on the back. I don't know what the repair
was, unless there is someone who has all the Tandy codes for the different
repairs possible. (If such a list exists) But I'm afraid that there is no
alternative but to open up my Model 100 and see if there was anything changed
inside. I'll take photos along the way, so that people who know - you know who
you are - can tell me if there is anything strange or modified on my '100.
Would changing the main ROM - to correct the trig error - also modify the
character set? Or are they located in different chips?

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
[..]
Anyway, the check can be done using the PI.BA program listed here, below or in
my file section on the website.
