060 is very compatiblble, 040 too. I had more problems with some 030 accelerators compared to 040/060 one when using the right libraries. 90% of time I use my 060 accelerated Amiga's, everything I use is working just fine (whdload, softwares such as wordworth, turbocalc, lightwave, sound trackers, amigaamp...).
Even a monkey like me can add a CPU on its sockets, I can't see where is the difficulty and how we can destroy something except the CPU itself.
Anyway thanks Jens for this new accelerators, even if I am not a "030 target" at that price.
