 they might be refered to as bucket delay chips. it is basicly an analog
 memory chip that shifts 1024 readings.

Hello
The Bucket brigade devices are made by Reticon.  I have used a very old
version of the 1024 bit device (SAD1024).  It was very difficult to use.
 Their newer parts are much easier to deal with.  They come in all bit widths
(256, 512 and 1024).
The wider the bucket brigade the deeper the echo effect.
