Hi,
Video 26 deals with loading and saving the front panel Pong program. In the support doc,
http://altairclone.com/downloads/pong.pdf
the loader and saver programs are listed along with the "octal dump for front panel entry."
The programs were written to utilize the SIO port (address 0/1). I'm wondering how to change them to use the 2SIO at 20/21.
I see in the program listing for the SIO the first two instructions reference 0/1. So I want to change those to 20/21. But what I'm not getting is how that would change the octal dump for the front panel. Can someone explain how to do this?
More generally, what's the relationship between a program and the octal dump of a program?
