Narrative:

The captain called 'set takeoff thrust.' I followed the autothrottle setting of the target EPR and called 'takeoff thrust set.' I moved my scan to the captain's airspeed indicator and watched the needle come off the peg and begin to rise. I moved my scan to the standby airspeed indicator and observed the same. I then shifted my scan to my airspeed indicator and observed normal indications and called '80 knots.' at approximately 90 knots the captain rejected the takeoff stating he had no airspeed indication. I noted the speed and called tower to inform of the reject. We were given clearance off the runway and instructions to contact ground control. I checked the brake cooling chart and determined we did not require cooling time and informed ground control we did not require assistance and received instruction to taxi back to our ramp. During taxi back we received several intermittent airspeed overspeed warnings accompanied by an EICAS ATC fault light and vmo; as and mach flags in the captain's airspeed indicator. The logbook indicated a previous rejected takeoff for an inoperative captain's airspeed indicator; with a proper sign-off of the discrepancy.

Title: A B757-200 flight crew rejected a takeoff when the Captain's ASI failed. Multiple EICAS messages following the event predict a malfunctioning CADC.

The logbook indicated a previous RTO for an inoperative Captain's Airspeed Indicator; with a proper sign-off of the discrepancy.
