The people in this video are opening Christmas presents probably in the 1940s or 1950s! Do you know these people? Are they your relatives?
We bought this old 8mm film at an antique flea market in Central Florida recently. I thought it would be fun to publish the video online just to see if anyone noticed their relatives in there. Feel free to share this video!
Click the Email Us link at the bottom of this website or add a comment below and tell me if you think you may know who this old 8mm film belongs to!
Several of my talks or speaking events have been recorded and published online. They are all different lengths. They are all about different topics. And they are all meant for different audience types and audience ages.
The list below should help organize the chaos and help you find the talk or presentation that’s right for you!
Kurt talks about NASA’s history of robotic exploration of Mars and also explains why we will need to find and use local resources on Mars along with different robotic technologies that exist to perform those tasks. Kurt then answers questions from the online audience.
Kurt talks about the NASA Swarmies which are a group of small and inexpensive robots modeled after ants that might be useful some day in the future for finding resources on Mars. Kurt then answers questions from the online audience.
Kurt gives a futuristic story based keynote that describes technologies that will be needed before we can send humans to live and work on Mars. And NASA is working on many of these technologies right now! This is a new and improved version of the below We Are The Explorers keynote.
Kurt compares the early pioneers to modern space explorers while also describing technologies that will be needed before we can send humans to live and work on Mars. And NASA is working on many of these technologies right now!
Kurt talks about the Swarmie robot project along with software technologies and techniques used on the project. He also goes into various challenges and solutions that were encountered by the development team.
This simple introduction to AppleSoft Basic is demonstrated on my working Apple IIe from 1983. It’s meant for beginners, so it doesn’t dive deeply into any one topic.
This 30 minute video lightly covers the following topics:
numeric and string variables
moving around the text screen
common error codes
procedural programming in RAM
editing and debugging
low resolution graphics
high resolution graphics
beeps and audio
If you want to try AppleSort Basic for yourself on a Windows PC, the best Apple IIe emulator I’ve found is called AppleWin and it is located here: https://github.com/AppleWin/AppleWin
Scroll down to the bottom of the GitHub page to click on the release link to download the zip file. Admin rights are not necessary. Just unzip the file and run the executable. Then click the Disk 1 button and choose the default (master) file. Then click the Apple button to boot up!
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!
This small Applesoft Basic program was published in one of my Beagle Bros Apple Software Catalogs from 1987 (volume 0, number 10). 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!
Wow! Write protect tabs! Amazing! 🙂
Applesoft 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.
Applesoft Basic was actually created by Microsoft for Apple. Hence the name. It is interpreted and not compiled, so it is not very fast. And it can throw syntax errors at runtime if it’s unable to interpret a line of code.
One sort of funny feature of Applesoft Basic is that variable names are only significant to 2 letters, although it allows more. 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. They are all three pointing to the exact same memory location.
Here’s the source code:
10 REM "MUNCH THE SNAILS!"
20 TEXT: HOME: H = 20: PRINT CHR$ (21): POKE 35,22
30 K = PEEK (49152): ON K < 128 GOTO 40: H = H + (K = 149) - (K = 136)
40 POKE 49168,0: IF RND (1) * 10 < 1 THEN VTAB 20: HTAB RND (1) * 20 + 10: PRINT "@": GOTO 70
50 VTAB 22: HTAB RND (1) * 39 + 1: PRINT CHR$ (46)
60 IF PEEK (1535 + H) = 192 THEN S = S + 1: VTAB 5: HTAB H: PRINT "#"; CHR$ (7): VTAB 23: PRINT "MUNCHED: ";S: GOTO 80
70 VTAB 5: HTAB H: PRINT "V"
80 T = T + 1: IF S < 10 THEN 30
90 TEXT: VTAB 23: PRINT S;" SNAILS MUNCHED IN ";T;" SNAIL SECONDS.": END
Once it starts, just click on the floppy disk 1 icon and choose the master disk file that comes installed with the emulator. Then reboot with the Apple button and it will boot to Applesoft Basic. Or, you can download ROMs for various Apple games and programs from the Internet and boot those instead. It emulates the speed of the processor, so it’s a very realistic emulation of the Apple IIe. Including several monitor types to choose from.
