Well , first, many thanks to all, now my Fastlane will be working ok soon ;-)
In response to amiga4001: AFAIK part of it should work ok under 060 with older versions of Z3scsi.device (version 5.1034 here also), at least the RAM expansion but the SCSI part will be just non operative
Today I put it back on my Amiga (A4000D rev.B, Buster rev.11 and with a Cyberstorm MKII 060@66 ) and booted from IDE ok and give no errors at all (well, no SCSI devices attached yet) but Scout tells that the the Z3scsi.device is present but couldn't be opened so here is the error.
And, as said Castellen before, I also find a Fastlane redundant if you have a CyberstormPPC, wich has its own UWSCSI controller (a lot faster than any SCSI-II controller out there...) and for the RAM expansion I think than the max. 128 MB of the CSPPC should be enough (for not to mention that this RAM is also a lot faster than the Fastlane's RAM expansion)
In my case using a Fastlane makes a bit more sense as I'm running an overclocked 060 and the Cyberscsi module for the CSMKII that I have does not tolerate overclock. So It's a way of bringing back SCSI to my amiga without loosing CPU speed downclocking the 060 back to 50 Mhz
