The Delay-Line Memory was a form of sequential-access memory used in early computers such as the Univac-I and Olivetti Programma 101.
It works by storing data as pulses in a medium such as mercury or torsional waves in coiled nickel wire.
A demo board has been created by P-Lab, showing the functionality of the memory with visual aids and LEDs.
The board runs at speeds of up to 150kHz and stores up to 64 bits of information, but does not support random reads and writes due to its sequential-access nature.
This is not the first vintage compute hardware creation from P-Lab, who are building a reputation for retro computing education via modern demo boards.
