ANDI.L #$00FFFFFF,D0 / MOVEA.L D0,A0 is, as you say, >highly< suspicious. Have you traced through to that point to see if the contents of D0 before that operation had something other than 0 in the high byte? That would seem to indicate their use of the high part of the address for other information, which would certainly screw up the CSA board! That's if they're making the assumption that the high 8 bits don't matter. The alternative is that they're using them for something but they >do< think they matter, which is why they mask them off with the above code. Have you searched AmigaBASIC for further occurrences of the bytes 00 FF FF FF? Maybe the problem is that it's overzealously zeroing the high byte of addresses that really are validly above $00FFFFFF. Removing the AND probably won't entirely fix the problem because they are doing that AND for a reason — probably using the high byte for something else — and you have to fix that code to use some other storage for that information. Ugh. Good luck! >Bela<
