Thanks - so far, I've confirmed what you are seeing. I'll dig into this and share what I find here. >Bonus: It does make quite the interesting sound when booting...

The straightline cycle count from immediately after reading the $AA nibble (at $BCB6) to reading the first read latch (at $31E) is 36 cycles (or 9 disk bitcells): ``` BCB6:BD...
