Hrm... why doesn't the floppy controller status register have its non-DMA bit set, even though I've used a specify command to set it... and why (probably related) do I get only a single IRQ from the read track command...? 💾⚡🖥

Life is a mystery. Alright I have coaxed 74 bytes of data out of the floppy controller. That's a start I guess.
