Hi all,

My SPARC-20 runs on a 50MHz MBus with a Ross 125MHz 512K cache CPU
(511-6424). I just found out from a Google search that most IT part websites
list 511-6424 as Ross 166MHz 512K cache CPU. One shows a Sparc-20 running a
66MHz MBus:

It seems to be a simple math of MBus determining CPU speed: 125*(66/50) =
166MHz. It also explains why some eBay auction claims 511-6424 to be 150MHz
CPU, because if you have a 60MHz MBus, then 125*(60/50) = 150MHz.

My question is do you know if any or all SPARC-20's MBus can be configured
to run at 66MHz?

All helps are appreciated.

Thanks
