Ha, the controller-ports comment reminded me of a project I built that used the Atari's joystick port to sample audio. You could increase the A/D sampling rate of the joystick port to 8kHz, so with a simple transistor circuit you could plug an audio jack into something and sample it (with the program I typed in from whatever magazine it was, probably Antic). Of course with only 32ish K available, you weren't sampling…
That's great stuff!! I had my HAM transmitter connected to those controller ports. Was a great resource, especially in the older machines that had 4 ports.
Way cool. Hey, if you’re still into HAM, did you see the article on here a couple weeks ago about commodities firms petitioning to encroach on the spectrum to execute trades a couple milliseconds faster? There’s an FCC public-comment form. Don’t have the link handy.
