Hmmmm.

i will check some stuff to see if there is a common pattern to this.

i know these romes where used on bally pinball pcb's
and my gorf pcb's are full of them.
+ i think they where used on the commodore pet and vic20

maybe certain revisions of apple-II pcb also used them.

i have not heard of these possible changes to pin config but it needs investigation.
