But there is a trick to circumnent this problem: the moment you run out of memory activate NRFD and NDAC at the right moment and the other CBM will think that the drive is busy and will suspend it actions for the time being. That will give you time to check the log and, if needed, to save it to tape (if possible ???). When finished, you release the lines and the show will go on.

Ah, that's a great idea! Anders probably already has 256 kB in his
CBM-II, so there's plenty of room for log data :-P
