Hmm, maybe Qube2700 and RaQ are 150MHz and Qube2 and RaQ2 are 250MHz
according to this page:

Open cover of your cobalt and check CPU on the board? ;-)
I could write some code to measure it, but if it's
actually model specific we don't have to write such code
(unless someone tried upgrading CPU clock)...

There are some variants of Rm5200 CPUs. (could be identified by rev?)
IIRC Rm5230 has 16+16KB L1 I/D cache and Rm5231 has 32+32KB,
but not sure.
