Re: A86: 5MHz




Well, if you enable the interrupt, it seems to take only about a second
longer (even less than that). So basically, Z80 seems to run same speed
interrupts or not... In response to battery voltage, the contrast level was
3, which I think is pretty low... if anyone with a (reasonably viewable)
contrast level of 2 can test it, that'd be cool to see, but based on
interpolation, even a contrast level of 0 would run at only ~5.5 MHz.
