In it mentions that The language ROMs were never replaced in the field due to a bug.

So while not a calculator as we think about them, it was marketed as a calculator and it had no bugs.


If the criterion is ROM replacements then probably many things qualify. Did the -45, -80, -65, -55 have ROM replacements? I guess technically the -45 had one to reverse the storage register arithmetic, although I wouldn’t put that in the category of bug. The museum has no bugs listed for the Stings or Woodstocks, but Bernhard started this thread talking about a Woodstock.
