Emerson Technical Sales personnel visit

• Emerson purchased the division of Motorolla that supplied VME single board processors.
• They continue to design new PPC boards and have just introduced an Intel-based board (Core i7).
• All boards run Linux and VxWorks. The Intel-based boards can run Windows (sorry, Beni...).
• Dave Abbott wants to move everyone to Intel-based boards, although VxWorks will be around for a while.
• Dave will purchase Emerson, GE-Fanuc and other boards, test them, and make recommendations to the halls.
• Full order from JLab for 12 GeV will be large, perhaps as many as 150 boards (maybe more!).
• Order will involve staged delivery and payment, back-end loaded as much as possible.
• Hall D needs around 70 boards, maybe more for spares and test setups.
• Hall D owns two GE-Fanuc boards; one is at IU and Dave has the other (for software development).
• Embedded processors use less power, but are less powerful.
• Emerson expects seven year processor family lifetime from Intel.
• New boards have lots of on-board memory, can boot from local memory instead of network if desired.
