Hi,
I just want to share with you my port to the Atari 800 of an really classic game.
The Last week I found and old magazine article, it's dated September, 1976. The author is Steve Wozniak and the Mag is my opinion the best mag of all times: Dr. Dobb's Journal of Computer Calisthecnics & Orthodontia
The program was written with the Apple 1 as the main target machine, but in the article (very short by the way) Steve put some instructions just in case you want to port it to other 6502 machines.
Now in 2010, when I finished the reading of this old piece of computer history I decide to port the game to the Atari 8 bit. In the process I founded an error on the Assembly Listing but I can fix the problem in a couple of hours.
I like to maintain the source code as close as the original as I can, but I be forced to make some changes in order to:
1) Assemble the source code with the cross assembler that I have at hand, adding comments identifiers.
2) Change the input / output routines for the Atari DOS Platform.
3) Fix the memory location of the "variables" because the listed version is not going to work on any machine (*)
(*) I think that maybe the Mag. published some fix on the next issues, but I do not have any number from those years... Im are 6 years old on 1976, I just start reading DDJ thanks to the father of a friend on 1989
You can read the original article including game instructions here
And the Atari executable here mstmnd.exe, a complete game on 333 bytes
