My unit also fails on the last 3 tests (direct 1 succeeds).

If I try Mia's suggestion to direct the bank to 0xf during reads of 
$0/$1, the ram test fails.  If I use $e, the ram test succeeds, and 
indirect 1 then works.  Direct and Indirect 2 always fail.

I verified that all tests work with the 6509 installed.
