I have a Nano hooked to the Sn76489 sound chip, along with a 4mhz crystal. I started wiring up a second one using my Teensy 2.0. I ran across code examples for Arduino that seem to say I don't need the crystal, and can using the CPU itself to generate that 4mhz timing.
Is this a thing? Possibly on Teensy 2.0? It would save me a part, if so.
