I was a bit surprised that it failed to do 10! ... the machine displays an out-of-memory error message. I think I was able to go up to the factorial of 7. This is a disappointing limitation for a machine with 500KB RAM!

Most likely, there's a fixed-size return stack that gets filled long before all of memory gets filled. That's unlike a PC where the return stack is limited only by the size of free memory.
