You can always try to do it yourself. If I were you, I would be bidding on this auction: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=150137282574 Does not have the ROMS, but Bob Roberts will sell them to you: http://www.therealbobroberts.net http://www.therealbobroberts.net/mpacroms.jpg Either Bob Roberts or Jameco will sell you a Z-80 processor. Of course, no guarantees on this route, you may have to do some debugging and research, but if I owned a PacMan it is the route I would be on... Just my $0.02 USD worth Christian
