The A11 6U board is a complete single-board computer designed for harsh environments but needs only one slot on the VMEbus. Being suited for VME64 applications as well, the A11 provides scalable performance from MPC603e to MPC740 at different clock frequencies. The board has 32MB onboard DRAM and up to 64MB SO-DIMM, Fast Ethernet, SCSI, serial and parallel interfaces, floppy, keyboard and mouse connections. Two PC•MIP slots permit flexible extension of the A11 by additional computer I/O functions.Industrial features such as onboard Flash, a CompactFlash slot, watchdogs, timeout and heat sinks make the A11's functionality complete. Signals from Ethernet, SCSI, keyboard/mouse, serial interfaces, PC•MIPs and CompactFlash are available on a transition module and alternatively directly at the front panel.
