Yep, that's just a speed rating. If it's running at 60 MHz then it's
likely the SBus part is running at 20 MHz, and might not be rated for
higher.
At best, I wouldn't try more than 80 MHz with a -85 and 100 MHz with a
-110 (20*4, 20*5).

> Romain you're likely right that a drop-in might not work out of the box unless the clock multiplication is entirely internal

IIRC, it runs at whatever clock is fed to it, then divides that by 3,
4 or 5 to generate the bus/system clock using DIV_CNTL, hence the need
to replace the oscillator/crystal/... that produces the CPU clock.

Cordially,
