> The last problem: your instruction specifies searching the translation tables with function code 7. Normally function code 7 would cause a transparent translation. In normal operation, the translation tables are never searched using function code 7. Unfortunately there is no description in the datasheet on how this special case is handled. So i guess it just searches the tables ... even when FC is 7.
There is a description in section 9.2.1 of the MC68030 User's Manual:
A CPU space address (FC0-FC2 -- $7) is a special case that is immediately
used as a physical address without translation.
