z/VM 5.3 Stacked RSU 5304

[Stricklin, Raymond J]

Folks --

Is RSU 5304 orderable on shopzseries yet?

http://www.vm.ibm.com/service/rsu/stk530.html shows 5304RSU current as
of May 20, but when I log in to ShopzSeries, the 5303 stacked RSU from
December 12 is the most recent of the orderable options.

Am I missing something or is it just not available yet?

Thanks;

ok
