Instructions

USE TURBOWARP AT turbowarp.org/726915061/ FOR FASTER SPEEDS! Well, after a few hours of work and a few weeks of deciding which system I should emulate, I finished my Apple 1 emulator in Scratch! How to use: When you first start up the Apple 1, it doesn't bring you to a BASIC interpreter, but rather a small program called WozMon. WozMon allows you to load programs using 6502 machine code represented in hexadecimal numbers, or load programs like BASIC from ROM or cassette (I didn't implement cassette support because of Scratch's limitations). Here's an example of a WozMon program: 40: A9 0 20 EF FF 38 69 0 4C 42 0 R (type this and then press enter) BASIC is already loaded into memory for you, so to load into BASIC, you can type in the command: E000R (press enter) then you can write a program like this: 10 PRINT "HELLO SCRATCHERS" 20 GOTO 10 RUN Fun fact: There is no backspace key on the Apple 1. Loading programs: To load a WozMon program, you can simply click the Import file button and follow the steps as shown. To load a BASIC program, first, load into BASIC by typing E000R and pressing enter. Then you can simply click the Import file button and follow the steps as shown.
