I think the 4p has a Western Digital 1773 controller. I don't know if it is much better beyond supporting double density. My code does wait on status checks after writing commands. Maybe that's not necessary, but I haven't done floppy drive programming before this so I followed the example code closely. Doing some speech recording back in the day -- heady stuff! I've always wondered how Big Five (and other) TRS-80 games managed to get reasonable voice output considering they are 1 bit/sample at 5 KHz. Takes me back, remembering how proud we were that our "baby" computers could speak. And now? Well, let's just say that I wish the "tab is producing audio" icon on Chrome tabs functioned as a mute button.
