Amateur Radio and the Apple II
At KansasFest 2020, I shared a presentation on the intersection of the Apple II and the amateur radio hobby. The slides are here.

I’m pleased to share yet another “Star Trek” themed game. I wrote this during middle school as part of a book report. Game play is terrible and amounts to firing weapons repeatedly with no strategy, but I was proud of it at the time. I wrote most of the game in BASIC with a machine language …

I’m pleased to share “My Summer Reading Log” by Georgiann Flowers, my 3rd grade teacher at Woodland Elementary School. To the best of my knowledge, she never published this software outside her classroom, and nobody has archived it online. This BASIC software for the Apple II tracks a student’s summer reading progress, including titles and …

In the first part of this series, we learned how to program the F18A using the AmpArcade library. We looked at loading the library, initializing the video hardware, and changing the backdrop color. While a good first step, that’s hardly interesting. In this part, we program the tile layer. The tile layer is versatile and …
This is the first part of my tutorial on programming the F18A installed in an Apple II. I cover installing the card and finding software. Future parts will cover more interesting topics, such as the tile layer, sprites, and F18A-specific features. Throughout, I’ll use VDP (Video Display Processor) to refer to the original TMS9918A, F18A …
Back when my Apple IIc+ was my only computer, I really wanted an ImageWriter II printer. This was “the” printer to own. It was reasonably fast, compatible with nearly all Apple II software, and printed in glorious color. Unfortunately, I was a kid with no job, and an ImageWriter II cost over $500. Needless to …

Here’s a poor photograph showing an Apple IIe running Sprite Logo for the first time. The left monitor connects to the Apple II’s normal video out, and the Apple CRT connects to the sprite card. The normal video out is useless while running Sprite Logo, which makes sense because most users wouldn’t have two monitors. …
Byte dedicated the August 1982 issue to the Logo language. This issue is an excellent cross-platform snapshot of Logo and its applications.
Next in my ongoing effort to document the world’s most expensive version of Logo for the Apple II, LCSI’s Sprite Logo for the Apple II Family, I show the included hardware sprite card. The board is a custom design from LCSI based on the TI TMS9918A video display processor, a video chip used in several …
Continuing my exploration of LCSI’s “Sprite Logo”, let’s break the shrink wrap and open the box. These photographs preserve the original packing order. Despite dirt and water damage to the exterior, the box contents appear pristine.
