Besides the clear screen button and reset buttons, is there any way to achieve the same effects, i.e. via monitor commands?

Thanks in advance!

The apple 1 had no way to clear the screen except with the clear screen button, thus the replica 1 is emulated with the same feature. This is also why backspace is an underscore _ It would be an easy program mod on the video firmware if you know how to program the propeller chips.

You could write a simple program to print 24 carriage returns in asm, but that would leave the cursor at the bottom instead of the top. Reset just points the PC back to the beginning of the monitor: $FF00, so a FF00R or 0: 4c 00 ff r in the monitor would do the same.
