  Hi!  Thanks for the replies.  Please let me further
clarify what I am
 looking for.  As part of the N8VEM project I do research into what sorts of
 designs are possible and practical for home brew constructions.  Part of
 that is researching what sort of home brew/hobbyist designs have gone before
 to see what has been done and how it was designed and constructed.
 Commercial solutions are available however they are typically proprietary
 and lack the important schematics and/or other design information I need. 
Why do you like to have it on ISA ?
There were few mc68k computers on VME, etc. which used the same
connector you use already on your other designs.
What wrong with that ?
Cheers
