A B767-300 appeared to have suffered the loss of the left FMS during the takeoff roll when the autothrottles failed to engage and the captain lost his command bars. Control was passed to the first officer who was pilot flying until alternate power was provided to the captain's flight instruments. After consultation with dispatch and maintenance control they continued the flight to destination.

Narrative:
Tower cleared us for immediate takeoff from runway 26R with company traffic on a 5 mile final to same runway. The captain set the thrust to approximately 70 percent N1 and selected thrust on the mode control panel (MCP) but autothrottles would not engage. I set thrust manually and called 'thrust set' and we continued the takeoff roll. Immediately after takeoff the captain noticed as he transitioned inside the aircraft that he did not have command bars and at about 200 to 300 feet gave the aircraft to me as I appeared to have normal modes displayed on my ADI. I called for heading select at about 500 feet and turned to our assigned heading. At 1;000 feet I called for VNAV and noticed the airspeed bug was at the barber pole not at the appropriate flap setting. VNAV armed but never became active. At 2;000 feet I called for center autopilot to command; the captain selected the C mode switch but it would not engage. He then selected the right autopilot and it became active. We continued the climb via flch and remained in altitude hold at all cleared altitudes as VNAV would still not engage. We never received any EICAS warning; caution or advisory messages as well as no status messages. There were no overhead lights associated with inoperative equipment or systems. The only indication was a 'no autoland' on the asa [autoland status annunciator]. The captain selected right on the instrument source select panel as well as FMC right on the navigation select and redirected the right side instrument data to his displays. We then contacted dispatch and maintenance control and explained what had occurred. They elected to have us continue and we concurred as the weather was good both enroute as well as our destination. The captain resumed pilot flying duties and I resumed pilot monitoring duties. We completed the flight and everything else was uneventful.
