Remembering memories

[schmitt trigger]

This thread may be considered a continuation of this previous one, but focused more on computer memory development:

It appears that the most primitive type of computer memory is mercury delay lines, which I have never actually used a computer which had one. My earliest computer experience was with a Control Data CDC3300, which had magnetic core memory.
My next computer experience was with an IBM 370/145, which already used semiconductor memory.

Anyways, a fun video on mercury delay line memory used on an historically significant computer;

im annoying to my former self

Not at all surprising.

My first contact with solid state MOS DRAM memory was 1103's. Also as a Production EE I had a
Mil project to manage the yield of a 256,000 bit PMOS shift register used for memory.
Initial yields were < 1 die / wafer. Before I handed it off we got to 5 die / wafer.
