 Ok, good point. I'm willing to compromise. Could you be convinced
to do everything execpt solder in the sockets? If the holes were
drilled, and the traces were there on the board, it would be trivial for
hardcore Amiga types to solder in the edge card connectors. 

 This would allow more Amiga expansion, but cause no problems at all for
those that are more inclined towards IBM expansion. You could even go so
far as to extend the IBM side of the bus (without installing connectors)
to give equal expansion opportunity. 
 
 This extend-the-bus-without-installing-the-connectors method is used by
IBM in the AT, and by Commodore in the A2000 (on two of the IBM bus
connectors). It seems to be the ideal way to provide more Amiga slots.
It would also give the A1000 + 2000-and-1 an expansion edge over the
A2000.
 
 Well, have I made a sale? Do I get any royalties? :-) :-) :-)
