These routines DO NOT EXIST on boot code 1.00, only 1.02 and above.

I'm pretty sure that's not correct. Are you sure you're not looking at an 83+ boot code 1.00 rather than an 84+ boot code 1.00?

Also, I would hazard a guess that these routines aren't actually meant to be called, but are reserved for future expansion :) FloppusMaximus 11:11, 5 March 2007 (PST)

You're probably right that they're supposed to be for future use. It was my understanding that boot code 1.00 on any calculator wouldn't have these higher BCALLs. If that's not the case, then what exactly is the difference between 84+ boot code 1.00 and 1.02? --Brandonw 06:12, 6 March 2007 (PST)
Very little, as I recall. Some minor changes were made in the USB initialization. The battery checking routines in 1.02 do something with port 3A, I think. I think 1.00 reports the archive size of the 84+ BE incorrectly. FloppusMaximus 10:04, 6 March 2007 (PST)
