morning bus from kurokawa onsen to beppu?

I've searched the net in vain for the JR Aso Yufu Kogen bus schedule. Links given by Japan Guide.com are broken. I'm looking a morning departure from Kurokawa Onsen for Beppu. The Kyushu Odan schedule shows two buses in the afternoon only from Kurokawa to Beppu. Can anyone help?

Here is the timetable for the JR bus through March 2012:

Kyusanko operates buses in the morning from Kurokawa to Yufuin, from where you can take the train or bus to Beppu. Alternatively, you could travel by bus and train via Aso:
