	J-PARC accelerator complex consists of a proton linac (LINAC), > a Rapid Cycle Synchrotron (RCS), and a Main Ring synchrotron (MR). The commissioning of LINAC already started in November 2006, while the commissioning of Main Ring synchrotron (MR) is scheduled in May 2008. Most of the machine components of MR have been installed in the tunnel. Introduction of electronic modules and wiring will be made by the end of 2007. For the control of MR, the J-PARC accelerator control network was extended to include the MR related parts in March 2007. IOC computers (VME-bus computers) for MR will be introduced in 2007. In addition, more server computers for application development will be also introduced in 2007. This paper reports the status of development for the J-PARC MR control system.

	An accelerator console system, based on a commercial thin client, has been developed for J-PARC accelerator operation and software development. Using thin client terminals, we expect a higher reliability and longer life-cycle due to more robust hardware (i.e., diskless and fanless configuration) than standard PCs. All of the console terminals share a common development/operation environment. We introduced LDAP (Lightweight Directory Access Protocol) for user authentication and NFS (Network File System) to provide users with standard tools and environment (EPICS tools, Java SDK, and so on) with standard directory structures. We have used the console system for beam commissioning and software development in the J-PARC. This paper describes early experiences with them.
