It just occured to me that, IIRC, when in 2 MHz mode the C128 goes back to 1 MHz when acessing the I/O-area. This would mean that all accesses by CPU allways are in 1 MHz :( If someone has a scope and C128 at hand, the only thing he has to do is to put the C128 in 2 MHz mode, to pull DMA to GND and measure CLK2.
