I don't expect that any EBAM has survived--I think all of the stuff I saw at CDC ADL was scrapped. Seems that the technology is all but forgotten today: https://bit.ly/2KOOl82 It's mentioned in a proposal by Neil Lincoln back in the 1970s: https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19770084287.pdf I've long thought that a scan converter tube (e.g. 7912) might make a good electrostatic memory. --Chuck
