I suggested that after the Final Countdown first computers are made with Rope Memory and Mechanical Relays. But Ken Schirriff said NO -- you need semifast semiconductors to read the memory.
- themafia 6mo agoI would love to see a relay switch at 1Mhz.
- timonoko 6mo agoYou will amazed. One reason is that relays are suitable for multilevel signalling. That is why the relays-only Fuji computer was on par with contemporary Amerikahito crap.
- monocasa 6mo agoYou'd be able to do it with tubes at least.
- Suzuran 6mo agoIf you have relays, the easiest RAM is just a bank of latching relays and the easiest ROM is a resistor board. Core rope is only for density.
- timonoko 6mo agoAchually. If you have L.M.Ericsson 8x8 latching crossbar switch, 64-bit memory needs only 6 relays. Yes SIX. The Fuji relay-computer has lots of those crossbar switches. However. The rope-memory in this scene is read-only-storage containing vast amount of data. Rope memory is economical to use but labor-intensive to produce.
