That comment says
”The Elxsi 6400, built in the early 1980s could do logical operations to memory using the off the shelf drams of the day. Designer was Harold (Mac) McFarland, of PDP-11 fame.”
I googled for more info, but didn’t find info about that. There’s a Wikipedia page (https://en.wikipedia.org/wiki/Elxsi) that confirms the McFarland part, and I found the system architecture (https://amaus.net/static/S100/elxsi/systems/Elxsi%20System%2...), which is interesting (instructions for multi-precision ascii addition and subtraction, for example, I would guess for supporting COBOL), but nothing about those DRAM tricks. Does anybody have more info?
