As I don't have core memory modules available, I thought of using MS11 memory, which, according to my research, seems to be an option for 11/40 systems. The system manual states on page 6-7 that the base power configuration consists of two H745 regulators and that one may be swapped with a H754 in case MF11-U memory is used. Does that mean that a single H745 regulator might be sufficient for my needs? All the best, Pierre
