  It shouldn't happen infrequently, it should happen not at all.  The design
of the 68000 allows refresh to be interleaved invisibly with the memory
accesses (look at how the coprocessors in the AMIGA work), so you should
NEVER have to resort to wait states for refresh!  If there ARE wait states,
I wonder about the design...

   Let's see...  2Meg = 72 256K rams @ $2.50 each -  180.00
                 Support chips (liberal)          -   40.00
                 PC board and case                -   25.00
 for a total of $245 manufacturing cost.  Given a 3 to 1 markup (not
atypical) that's a cost of about $750 that I would expect to see.  $1500
for 2Meg with current chip costs is a rip-off!
