[sdiy] CCD Chorus?

[Jerry Gray-Eskue]

Interesting, the delay module was apparently potted and the module design
never made public.
According to this site the CCD was an imaging sensor.

I recall that the CCD device was a spin off of observing the charge decay in
a DRAM chip when exposed to light. Makes me wonder if there are any DRAMs
that might be used as BBDs. The last time I took a look at this I think
there was no way to get at the voltage levels in the cells. Now an image
sensor makes sense as you read the voltage levels to capture the image. The
trick to making these work would be the ability to address and storing
voltages to individual cells.

I seem to recall the Marshall Time Modulator (designed by the inimitable and
much missed Steven St. Croix) used some sort of super-specialized CCD?

My google fu is bring up questions about it and references to it, but not
solid answers, but then my google fu is lazy this evening.
