Jan asked: Would changing the main ROM - to correct the trig error - also modify the character set? Or are they located in different chips?
There is only one 32K system ROM. So the system ROM in your Model 100 definitely is "repaired" in the sense that the trig error is corrected and it includes the Pi character. In other words, that particular Model 100 acts like a Model 102!

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?
