I'm glad you got it working.
A circuit like this would provide that protection. It's a more stable, filtered power supply that also allows the Mac to send (on MCU_RXD). The diodes should be Schottky types:
It has a positive and negative supply (V1 and V2). V3 is a clock signal.
If your rails come from the TX lines, multiply the two resistors by 5-10x to reduce current.
The math works the same as parallel resistance.
If you measure the impedance of a single transformer at 230.4 and 460.8 KHz, you can divide those figures by the number of adapters connected.
I don't get how feeding TXD- and TXD+ directly into a transformer is safe. Is there never DC across them?
I make those and they do work. You can check the item feedback.
It prevents contact with the sticky rubber and won't interfere with the parking mechanism.
You don't need to expose the drive internals more than this:
It is not.
BIN is a 2352 byte per sector rip of an entire disc. The track layout is described in a separate CUE/TOC file.
ISO is a 2048 byte per sector rip of just a single data track. The extra 304 bytes of error correction, sync, and other data are discarded in this format.
The IMG and...
My best guess based on its size, 250mW.
No, the peak to peak was only 6.8V. I set the volume to 7 and played all kinds of sounds. 6.8V was the max Vpp the scope recorded.
I used a 100Hz sine, but it doesn't make a difference. I simulated the speaker as a resistive load, which is worst...
I ran some simulations with 63Ω, 8Ω and a dead short. The highest peak to peak voltage I recorded from an unloaded SE/30 speaker header was 6.8V, so I simulated with a sine wave with the same peaks.
63Ω speaker: 21.8mW
R10: 9.4mW
Q1/Q2: 54.1mW
8Ω speaker: 17.7mW
R10: 59.8mW
Q1/Q2: 170.0mW...
