3 jan 1961 ano - Magnetostrictive Delay Lines

Descrição:

The Ferranti Sirius is announced. The Sirius was a small, low-cost business computer using a simple programming language. Its main memory was a magnetostrictive delay line. The medium here was a thin strip of special metal rolled into a coil, with transducers at either end. Like all delay lines, bits were fed into one end, detected at the other, and continuously recirculated. Although this type of delay line was considered to be somewhat slow, its low cost made it attractive to computer designers.
