I don't think so. The glue logic are very simple and the PCB area are
minimal. In this configuration, you have another bonus that you can use
DoC 2000 which is much cheaper than DoC Millennium. IIRC, Brian
Stephenson has made some of this long time ago. He also sent me a
schematic diagram for the "socket" he invented. Unfortunately, I can
not find anything about this left since my last HD crash. It also seems
that Brian Stephenson has left us and is no longer on the list.
