I think you want the DPC (aka Pitfall II chip), right? checkout US patent #US4644495 on the IBM Patent server. www.patents.ibm.com 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. :) -Chris -- Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
