Concurrent Technologies is shipping two low-power, single-slot VMEbus single board computers (SBCs) that support Linux. The VP 325/02x has a 1.6GHz Pentium M processor, while the VP 327/02x can be fitted with either a 1.8GHz or low-voltage 1.4GHz processor (the latter supports extended temperature environments).

Both SBCs support up to 2 GB of onboard 333 MHz DDR ECC SDRAM, with up to 1 GB soldered directly, and another gigabyte added via an SODIMM socket. A 64-bit Intel 855GEM chipset provides graphics resolutions up to 2048 x 1536 at 75 Hz, with rear-panel DVI-D and front-panel VGA outputs. An onboard PMC (PCI Mezzanine Card) expansion module location boasts 64-bit, 66 MHz PCI operation with either 3.3 or 5 volt signaling.
