Apple ][ Graphic Adventure Part V

Now that my memory issues are seemingly under control, let's take a look at my modifications to the parser. Normally, in these types of graphical adventures the player enters two words in the form of VERB OBJECT. My interface limits the number of verb choices and allows the player to enter a verb with a single keystroke.

Apple ][ Graphic Adventure Part IV

Previously I discussed the overall structure of my soon-to-be hit adventure game. Well, last night was a milestone. I managed to write an Applesoft program so epic that it overwrote the high-resolution graphics page. Compared to other programs I have seen, mine isn't that huge. Around 250 lines isn't that huge, right? Transylvania clocks in at 464 lines.

Apple ][ Graphic Adventure Part III

The previous post in this series explained how to get Graphics Magician images to display from Applesoft. Now, I'd like to go over the structure of the program listed in Write your Own Adventure Programs. The bulk of the program listing consists of the game data including objects, room descriptions, verbs and state flags. Most of the remaining code is comprised of a series of conditions that check how the player's actions affect the objects in the game world.

Apple ][ Graphic Adventure Part I

Having recently played the Apple ][ game Transylvania and its sequel, I was inspired to mess with the art program which those games used. The Graphics Magician was a huge hit for Penguin Software, but I never actually had a chance to use it when we had an Apple ][. I just remember it being advertised in every computer magazine I had.

Some Yamaha DX100 / DX27 Synth Patches

I've owned a Yamaha DX100 synthesizer for decades and never really had a strong grasp as to how the heck you build sounds with it. The last few months I have been immersing myself in FM synthesis and I think I finally have a handle on the concept now. Here is set of twenty-four patches that I created:

You Can Now Buy My Art on Etsy

I've been using this Web site as a place to show and sell my art for nearly twenty years. In that time I have sold exactly zero prints. I know I haven't exactly been P.T. Barnum when it comes to self-promotion, but seriously, zero? I have even offered prints for free with no takers.

Well, today is the day that all changes. I am now selling my prints on! This means they'll handle the billing and shipping calculations and you can sit back, relax and send me all your money!

The Music Studio Instrument Samples

Jump For LOVE!

I recently took the time to sample all of the default sounds from the Apple IIgs music composition program The Music Studio for use with my new sampler. The sounds were recorded directly out of my IIgs via an Applied Engineering sound card and into the Octatrack. I then took the WAV files into my PC and cleaned up the audio a bit. The IIgs outputs a rather noisy signal.

The Podcast Report

Today is supposedly International Podcast Day. Well, let's celebrate this phony-baloney holiday by taking a look at some of the podcasts that I've been listening to lately. I feel like this list will change as time goes by so I wanted to document it here for future reference. These are in no particular order so here goes.

Political Word Trends

The current presidential election cycle has made Facebook insufferable these days. As the various screeds flow across my feed from people who would normally be reasonable friends, I am noticing what I am calling, "political word trends." Out-of-the-blue people start using the exact same words to describe something with which they have a political beef. I know this is essentially the same thing as talking points (like when every Democratic operative on the planet described Hillary "powering through" her illness), but what I am seeing is just a little more subtle.

Apple ][ Assembly Language Programming

The past few weeks I have been diving into the world of assembly language programming on the Apple ][ computer. My interest in the topic stems from the recent book release of a compilation of articles on assembly language programming called Assembly Lines: The Complete Book. The articles were written by Roger Wagner and originally published in Softalk magazine back in the early eighties. This edition was edited by Chris Torrence and is available for download and purchase from a number of locations.

Now, I am pretty familiar with Applesoft Basic programming, but I was always in awe of commercially released software on the Apple ][ that ran so fast, had fancy hi-res graphics and used sounds other than the system beep. What was the secret of these mythical programs that required you to type "BRUN" in order to get them to load? The secret was machine language.

Major Overhaul of Planet Pimp Web Site

Did you know I maintain an informational resource page dedicated to Planet Pimp Records (the greatest record label ever to exist)? Well, now you do, and today I uploaded a massive update to the site. This is mostly behind the scenes stuff that makes the site easier for me to update, but I have also added some new features including links to external video and audio. There have also been some fancy style tweaks so the site now scales to fit mobile devices.

My First Foray into SASS

As I mentioned a few posts ago, this site has received a major theme overhaul. Aside from a couple form element styles, this change was mostly structural and behind-the-scenes. The new theme is my first foray into using the SASS CSS preprocessing language. Let me tell you, it was a revelation. SASS allows you to write CSS using a super-clean tabbed coding style and (finally) allows the use variables and expressions in styles.
