Nope.  My Ronin board has one wait state.  Ronin claims I can change an
R/C time constant to run it at 0 wait states, but not only do I need 80ns
RAMs to do it, they can't guarantee that it will work.  Not very
reassuring.

I was under the impression that the Commodore card was one wait state
as well, so I'd expect equivalent speeds.  I'll post benchmarks if
someone with a 2620 will.

A not to be forgotten fact, though, is you can't DMA into Ronin memory,
which slows my lightening-fast CDC Wren III/SCSI/DMA drive dramatically.

Just my experience.  I'm getting a 2620 to replace my Ronin and am
taking bids . . .
