What's also interesting is that on 68000/OCS COPCON ($dff02e) apparently allows to write to the blitter registers as soon as it's not zero anymore, i.e. it's not necessary to explicitly set bit #1 (CDANG), any will do (Hardwired bug, bset #1,$dff02e). On AGA/680x0 this doesn't work and seems to completely freeze the copper.
