Like Dale said (and he should know…) the power supply isn't a real problem. That "Tick" signal the 2000 & 3000 used was just a 60Hz signal from the power line. I looked at it once with a scope, and it looked like someone took a sine wave and lopped off the tops with a zener. 🙂 It could be added to a stock PS.. Not only that, but the 500/600/1200 don't even use that signal, the power brick doesn't have it. I was figuring on changing the hardware to support standard drives. There's no reason to bother with that Motor/Ready business in a machine with a power supply the size of a 2000/4000. They only did that so all of the drive motors didn't start at the same time and stress out a 500 power brick. The other thing was distinguishing between 5.25" and 3.5" drives. I don't think there's any need to support the 5" disks any more. It sould be possible to use a standard floppy controller chip instead of upgrading Paula or it's AGA replacement… Why reinvent the wheel? You'd have to change the trackdisk, which seems doable.. At least, to steal a line from Dennis Miller, "That's my opinion, I could be wrong." 🙂 -Jim MOS via Autopilot & Amiga
