Without further ado, here's my really big PEEKs, POKEs, andCALLs and stuff list.Ī little more ado:As always, feel free to email/post to me questionsabout this stuff. Someof the info may be less than 100% accurate I haven't updated this in along while. Asusual, I claim no responsibility for any damage, etc. Some arefor ProDOS, some are for DOS 3.3, and some are for Applesoft BASIC in general.A lot of the DOS 3.3 stuff came from Bert Kersey's DOSTalk Scrapbook. You've probably seen a lot of these before, but you may still finda useful P,P, or C that is new to you (assuming it works! : ) ). Including several monitor types to choose from.Apple II - PEEKS, POKES & CALLS Main | Links | Downloads | Apple // Texts | Apple // Specs | The "Sider" Hard Drive It emulates the speed of the processor, so it’s a very realistic emulation of the Apple IIe. Or, you can download ROMs for various Apple games and programs from the Internet and boot those instead. Then reboot with the Apple button and it will boot to Applesoft Basic. Once it starts, just click on the floppy disk 1 icon and choose the master disk file that comes installed with the emulator. It’s in a zip file, so just unzip it and run the executable. Just scroll down to the bottom of the Github page and download the latest release. It’s just not terribly robust.Ī very robust option is the standalone Apple II emulator program that you can install onto your Windows computer. There are some things that this emulator cannot do, though. If you don’t have a working Apple IIe of your own to try your Applesoft code on, you can first try it in a JavaScript implementation of Applesoft Basic. They are all three pointing to the exact same memory location. So if you initialize a variable named “KURT” to a value of 10, you can PRINT the variable “KU” and also the variable “KURT” and also the variable “KUPP” and they will all three show a value of 10. One sort of funny feature of Applesoft Basic is that variable names are only significant to 2 letters, although it allows more. And it can throw syntax errors at runtime if it’s unable to interpret a line of code. It is interpreted and not compiled, so it is not very fast. Wow! Write protect tabs! Amazing! □ Applesoft BasicĪpplesoft Basic is the programming language of all the early Apple computers and was provided in ROM (memory) to make it available to the user without the need for a startup disk or the need to load it into memory from a cassette tape.Īpplesoft Basic was actually created by Microsoft for Apple. This little program was credited as being submitted by Beagle Bros customer Tim Boehme, who received a box of Beagle Bros magnetic write protect tabs for his efforts! This small Applesoft Basic program was published in one of my Beagle Bros Apple Software Catalogs from 1987 (volume 0, number 10). If we type this simple 8 line Applesoft Basic program into my working Apple IIe computer, we will end up with a cool little text based arcade game! Watch the video below to see the game in action!
