- I _think_ he needs a tower. The "tower" was created become an overworked engineer
- routed the ROM board traces mirrored. (Don't laugh, once I put new spark wires on
- a car in exactly the wrong rotation around the distributor, took us a good rest to
- realize what was wrong ;) The tower is a printed circuit board which
- plugs into the upper pair of rom sockets, via a standoff, and holds the new
- ROMs upside down.
-
- Furthermore, the screenprint for U180/181 are reversed on _some_ A3000s. I'm not
- sure if this is only on the tower. You can try the upper (1.3) ROM sockets, but
- reversed, if you haven't.
-
- You will probably have to contact an Amiga repair/used equipment dealer to find
- a tower. I can look one local up, if need be.
