Ack!  I just lost the newest in this thread.  I think you want the
DPC (aka Pitfall II chip), right?

checkout US patent #US4644495 on the IBM Patent server.

Note:  you're going to need external rom storage, or a really big logic
chip.  I looked into this a while back.  It's doable, although there's
some timing issues = analog components (or counters).  Right now, I think
that's about #5 spot on my projects list. :)
