A "faux-tograph"! (snicker). Couldn't resist.
Where there is a will, there is a way. Here, in the current environment, where there is a severe chip shortage, it is nearly impossible. Yet, if the market reaction...
My thinking was that I don't want to destroy any of my good equipment on the first go-around - I really have no idea what is going to come out of these old chips. These little speakers are... disposable :D And they can...
@Stephanie-Wallace , do you think I can use these (or similar) with the audio shield? At least to get started?

Good point. But, like you said, these pokeys are getting harder, and more expensive, to acquire. Although, it does seem like some in the Atari community are trying to develop pokey replacements, and the like. PokeyMAX...
Oy - tell me about it! I'm so nervous handling these things.
Yeah, I looked at the NXP application notes a while ago, but I couldn't find the way to create the 6502-style parallel bus. The sample file that was...
Great! That's what I was hoping you'd say; I will definitely use that to mix the two chips for stereo out. I'm now checking to see if I can acquire any more of these (assuming that the price is reasonable). I don't love...
Yeah, the schematic is very helpful - great find! And, yes, I do find myself using logic level converters often, because all the vintage/retro stuff has +5V logic. So, I have a handful of 8-bit shifters handy. I also...
Here’s a simple question, @Stephanie Wallace . Can I simply run Pin 37, audio out, from a pokey into one, or both, of the Line Ins on a Teensy Audio Shield? Would I need any resistors, or anything else, to connect that...
That's very cool (and thanks for sharing all that!). I got into retro electronics during COVID, revisiting the ins-and-outs of 70s, 80s, and 90s retrotech that I never really delved into in their day; for the most part,...
Yeah - I just shelled out for another one. Ya know, just in case. I like to have a back-up.
You seem to be quite enamored with the YM2149. Any particular reason(s)?
Well, you seem to know a bit about this! Since I'm not reading a keyboard or potentiometers, is there a minimal setup I can use? What about the audio output (Pin 37)? Does that need to go to an amplifier? I would...
Thanks. Starting with the basics, is this something to be bit banged, or is something more elegant and precise required? What about clocks? I only have one, so I guess that precludes stereo?
I have a copy of Atari 7800 "Ballblazer," which contains a Pokey sound chip. If I desolder it from the board, is there any way to "use" it (for playing music) via a Teensy 4 or 4.1? I also have a teensy audio board...
