By the way, for those who don't know, CADET stands for "Can't Add, Doesn't Even Try": the add and multiply tables were stored in unprotected, normal speed (20 usec) core; the most common bug would result in wiping out all memory, and your ability to add. But having a writable add table meant you could add and multiply in bases other than 10. The console terminal (modified typewriter) on our machine was not overlapped: if you held onto the carriage when it tried to carriage-return, the whole machine would stop.
