Line 4622 actually seems to be the place. Thanks!

Thanks! I should add that this occurs with programs that work correctly on
other EVBUs. So I'm guessing defective static RAM chips.

Hey thanks for posting that. I have a class with the HC11 and the
BUFFALO monitor. My professors wanted us to ask for it instead of
making it freely available.

Looking at this asm listing (line 635 and beyond):
http://www.ecse.rpi.edu/courses/CStudio/hc11/buf34.lst
It appears that this is a memory write/read-back error (most commonly
an attempted write to ROM, I guess they assumed, hence the error name).

Greetings,
I'm not very familiar with the Motorola 68HC11 but am teaching a course
using it. What does it mean when BUFFALO gives an error message such as
"ROM 2000" or "ROM 1384"? I don't recall the circumstances under which the
error was displayed (I'm working from old notes about what is wrong with
some of our defective EVBUs). Easy to fix?
Thanks!
