See that highlighted line? Yeah, young Ray didn't notice it. I went back to the manual, and read past the lines of code. I'd look at the manual, look at the screen, go back to the manual, and I just had no clue. I swear I looked at this for hours (most likely it was far less than that) and I just couldn't figure it out. Here it is recreated in the Windows AppleWin emulator: I'm old, but not that old.)Īnyway, I followed that text very carefully, and when I ran it, I got an error. (And to be fair, it was a hell of a lot better than using punch cards. Never complain about writing code in Notepad again - this was truly old-school coding. This lets you "slip in" lines of code you may have forgotten. The typical program would use line numbers counted by ten. By default, execution will go from the lowest number to the highest, but basic jumping around was supported as well. Here's where I got stuck:īASIC programs consist of lines of code preceded by line numbers. This was a good manual, but I quickly ran into an issue, and by quickly I mean on page 2. My manual was the Applesoft BASIC Programming Reference Manual: Shoot, I'd sometimes write the same simple program multiple times just to see the result again. It's hard to describe just how exciting that was - having a development environment as a default meant I spent a heck of a lot of time writing programs. Applesoft BASIC was a simple language, and best of all, you could literally turn on your machine and immediately begin writing programs. So at some point, I stopped playing the games (err, well, stopped playing the games exclusively) and took a stab at trying to learn to program. While I was pretty young, I definitely knew it was fiction, and working with computers wouldn't be quite that cool, but it really fired up my interest. At around the same time, I saw a movie that had a huge impact on me. My mother's employer sent her home with an Apple 2 (either the Plus or E model, I forget which), and while it was supposed to be for her, it also included a bunch of games, so I immediately became attached to it. My interest in and introduction to computers came at a very early age. Matteo Trevisan an Applesoft Hobbist Developer.I've told this story a few times before, but I don't think I've actually ever shared it on my blog. To load an Apple II game or program inside apple 1 simulator write CATALOG at the prompt then LOAD and name of With 0300R Then F3, select Integer image inside Apple 1 Folder Then CATALOG and then LOAD HELLO and RUN, return, you go in INTEGER BASIC, otherwise you can load it pressing F3 in the emulator and selecting Integer image inside Apple 1 Folder. I have made a little modification in the code that display the prompt screen like in a real Apple 1. With 0 A9 0 AA 20 EF FF E8 8A 4C 2 0 you run the text monitor remember to write R and press RETURN. To the code and adding a call with 0900R in the prompt. I have add the game from Apple 1 "ROCK PAPER SCISSORS" by makeing a porting for Apple II and adding it With 0700R you can run SHALL WE PLAY A GAME mini game. With 0300R to go to BASIC, with 0500R you can run a Simple Calculator, With 0100R I have built a program that show free variable mem. To exit the first two screens press R return and * return respectively. A porting from Apple 1 ROCK PAPER SCISSORS for Apple //e made by me. This is an Apple 1 for Apple //e Simulator, I have added one program and two games in the Apple 1 OS, one Simple Calculator and SHALL WE PLAY A GAME? made by me. To load it use AppleWin for Windows, Linapple for Linux or Virtual II for Apple Machines. This is a ReactiveMicro wiki page about the Apple II.
