Johan,

It's a BBC B. Everything (BBC, drives, GoMMC) is working like a charm.

I've got the BBC/drives for 2 years, no problems at all.
What's the patch for 3.5" drives? Software or hardware?

>> Can anybody shine some light on the fact that the Z80 goes into HALT-mode?
> Not sure though that an DFS issue can halt the Z80?
No idea. The fact that the ROM of the Z80 and the image I got from  
internet are not the same is not giving me a warm feeling;).
I can check the differences this weekend.
