One thing that would be interesting to know... if you put only one ARMSID into the MK2, then configure the chameleon for "mono" - does the config program work now?
I'll try it later.
What Martin from ARMSID said tom me is this:
The ARMSID and ARM2SID will definitely not work with different bus timing. The read is sometimes pretty tight. We do not have the Turbo Chamaleon 64, so we were not able to test ARMSID and ARM2SID with it. We did not have any reports about it until now. Let me know if you find anything.
