You're both right. I forgot the word "MAXBSIZE" ! The correct message was
	panic: buffer larger than MAXBSIZE expected
It's also correct: the /zip1 contained a FFS-type filesystem (source). 
But the destination exactly was the terminal (only listing tar-file - 
t-option). May be this messages comes, because I changed the media just
before the above command from a MSDOS-type fs to ffs.

follows soon (tonight too late).

Tja, my question ! To help to clear my hardware I can say that my actual
Falcon has a NEW motherboard which is very newer as my last one of last year;
this is from about first quarter of 1993. But the disk is a very old MFM-disk
from about 1988 from CDC-WREN V or something (588 MB raw disk space).
However the ZIP (IOMEGA) is very new (from Oct 1995)

Haeh' can you explain this a little ??? What happens, what is the difference
when Falcon is switched of a _longer_ time or a _shorter_ time ?
