The comparisons of size, power, storage, cost, power usage, heat
output and so on are often made.

Oregon Status University constructed a general purpose computer (Nebula) in the

main memory with an auxillary 2k Content Addressable Memory with 32 bits plus
some 'tag' bits.

I don't know about that one, but a delay line is a key component of a PAL
(European) system color TV receiver.

Wasn't some of this glass delay line memory used in early raster-scanned
computer video displays?

Interesting stuff. When I saw Corning I thought glass fiber (optical pulse

Hey all, found this on eBay:

I can't find any info on it - was it some kind of delay-line or magnetic
laminate stack?
Interesting!
