Steve,

thanks for that detailed reply. I think I got it :)). Unfortunately I
missed (in the Apple II related forum on Delphi) a "bulk" (if you can
say so) purchase of 68040s for really cheap (about 30$) and now I'm
looking for another source. *IF* the dealer is trusted overseas deals
aren't a problem at all :))

Best regards,
