(Editor's note: a Usenet post by David A. Newman states that board revision 2.4 is the most current, with 2.3 and 2.2 also available. Revision 2.2 boards under serial number 31001650 may require a patch by Phase 5 Germany to work with a Broadcaster Elite or DBC32. Use with a 68060 may require a new ROM from Phase 5.)
