CDC 1604 (1959)
O CDC 1604 era um computador mainframe de 48 bits , projetado e fabricado por Seymour Cray e sua equipe na Control Data Corporation [2] , lançado em outubro de 1959 [3] para se tornar um dos primeiros computadores transistorizados de sucesso comercial .O processador rodando a 208 kHz continha um acumulador de 48 bits (A), um registro de máscara de 48 bits (Q), um contador de programa de 15 bits (P) e seis registros de índice de 15 bits. -

IBM 7094 (1960)
tHe IBM 7094 achieved expanded power through high-speed processing by providing its user with
A basic machine operating cycle of 2 microseconds
A new processing unit which had major speed effects on:
Floating point operations fixed point multiply and divide operations
Index transfer instructions
Two instructions per core storage cycle, substantially reducing instruction cycle time
New expanded functions provided with the IBM 7094 were: double-precision flo -

CDC 3600 (1963)
he Control Data Corporation (CDC) 3600 computer arrived at NCAR in November 1963, but the operating system was not ready. SCD staff put together an operating system sufficient to be able to utilize the machine, and by early 1964, SCD was able to provide service on the CDC 3600. By the end of 1964, usage had grown from 50 to 300 hours per month and SCD had run approximately 19,000 jobs. -
UNIVAC 1108 (1964)
1108 Multi-Processor Systrem
Ref: UP-4046 Rev 1
The UNIVAC 1108 was the second member of Sperry Rand's UNIVAC 1100 series of computers, introduced in 1964. Integrated circuits replaced the thin film memory that the UNIVAC 1107 used for register storage. Smaller and faster cores, compared to the 1107, were used for main memory.
In addition to faster components, two significant design improvements were incorporated: base registers and additional hardware instructions.
