And now it's at 176MHz.. incredible.
Actually, those MHz figures are slightly misleading.
There are several versions of the BBC Basic benchmark, calibrated for different versions of BBC Basic.
The one that I have been using is calibrated for Basic II, but the BBC Master I'm testing on is running Basic IV. In BBC Basic IV the floating point code is much more efficient, hence the tendency for the Benchmark to over-state the equivalent 65C02 frequency in MHz.
This morning I dug around a bit and found the version that's correctly calibrated for Basic IV:
If we can get to 140MHz on this benchmark, then a 700MHz ARM will be emulating a 6502 at 1/5 of the clock speed.
