there is a chip that is an analog delay chip. digikey carries them. i think
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.

       I had one of the old SAD1024 Reticon devices in 1979.
I remember that the clock required two signals which complimented each other
but that meant only that you had to use an inverter for one of the signals
and then feed the oscillator directly to the other clock input.  I didn't
know that one could buy modern versions of the SAD1024.  Mine worked very
nicely until I zapped it with static electricity through mishandling.
at $12.00, that was an expensive lesson.

       What was bad about the older SAD1024's that has been corrected in
the present delay chips?  I never tried to cascade a large number of them
or use then in anything sophisticated.  All I did at the time was to
connect the two 512-bit halves of the chip together and then play with the
audio delay that resulted from the full 1024-bit register.
