Hi All I have been notified if another mistake in the configuration.txt doc (thanks to Frank Agnew) which I've now fixed. In the cpu_type section, if you want to use an 020 with FPU, then the correct values to use are '68ec020/68881' and '68020/68881' - not '68ec020/881' and '68020/68881'. Apologies to Dan if this causes you more work. ;-) You can download the updated file at: http://rcdrummond.net/uae/test/configuration.txt The public CVS at sourceforge will probably take a few hours to catch up. Cheers, Rich
