Talk:IBM 2260

This does not make much sense without a lot more explanation

It is like storing data on a long microwave link (also done, in the 40s or 50s). But if one doesn't indicate if there is a multiplicity of e.g. time slotted pickups for different terminals AND that the pickup feeds back to the voice coil to keep memory alive, the question arises: why on earth? Why the delay? Why not electrical signal straight to VDU?

AND, where is the delay line? In the terminal? One at each port in the controller? Where did the multiplexing take place? Ahead of each dedicated delay line memory? Or downstream from it? In the time domain?

NO. A delay line is a FIFO device. Open ended. No loop. Where is the loop? — Preceding unsigned comment added by Spamhog (talk • contribs) 11:46, 1 October 2011 (UTC)
