Is there anything the WD chip won't handle versus
a raw track
approach?
Any format not derived from the IBM SD and DD standards.
- HP 300
- DEC RX02
- TI FD1000
- INTEL M2FM DD
- AED 2500 and 6200
- AED WINC05 5"
Eric and I built a sampling reader as you suggested a while back.
I would suggest storing deltas between transitions, measured at a
much higher rate (from memory, Catweasel can delta at up to 40MHz
resolution)

From the catweasel 3 docs:
Setting clock speed:
To set the clockspeed with the CatOption register, reset the memory counter
to 0 by writing 0 to the CatAbort register. Writing 0 to CatOption will set
the clock rate to 14Mhz. Writing 128 (0x80) to CatOption will set the clock
rate to 28Mhz, and writing 192 (0xc0) to CatOption will set the clock speed
to 56Mhz (to be precise, 56.644Mhz).
