I was looking for something else and stumbled across this.
The smaller capacity 256-bit (128 by 2 bits) "production" device was in a similar vacuum tube envelope. It was built with two storage arrays of discrete "eyelets" on a rectangular plate, separated by a row of eight cathodes. This version included visible green phosphors in each eyelet so that the bit status could also be read manually.
