Hard to say, without the modules they came from. As far as my (limited) understanding of vacuum tube logic goes, double triodes were very common for implementing basic boolean logic functions. Therefore, most IBM vacuum tube computers and data processing machines would have hundreds/thousands

PDP-10 was 36-bit. You’re thinking of the PDP-1, 4, 7, 9 and 15 line of computers. However, it’s not actually 18-bit, but 2 8-bit bytes with parity for each byte. If it is indeed an early Intel memory addon for minicomputers, i’d expect it to be for the 16-bit DG Nova or PDP-11 line of
