UNIVAC+494

a 30-bit [|real-time] mainframe computer system by [|UNIVAC] introduced in 1966, and member of the modular [|UNIVAC 490] series. The 494 has a memory cycle time of 750 nanoseconds. Core memory starts at 16 KiWords and was expandable to 2 x 128 KiWords. The ALU features [|ones' complement] 30 and 60-bit integer arithmetic, 60-bit or 10-digit [|BCD] arithmetic, as well as double precision (1:11:48) [|floating point] arithmetic. The programmer had access to seven address modifying 15-bit [|index registers] (Bi), one 30-bit [|accumulator] (A) as well as one 30-bit auxiliary arithmetic register (Q). || toc =Chess Programs=
