Hello

I don't think using direct emulation of the hd6301 would help, the 
problem is not in emulating the different commands in the ikbd, they're 
rather well documented so the behaviour in Hatari should be correct.
The problems are more in the exchange between the ikbd and the acia, and 
the respect of all bits in the control/status register, as well as the 
serial timings.

(besides, I think that integrating the hd6301_cpu.c in order to replace 
ikbd.c would take more than a few days :) The cpu might look simple, but 
emulating all the IO ports and their timings is the real challenge)
