The machine has a full 32KW of core memory. This is in two MF11-L
backplanes. The first contains 3 MM11-L board sets, each consisting of
a H215, G110, and G231. The second backplane contains one MM11-L. The
H215 is an 8K by 18-bit memory stack: two additional bits are available
for parity, but this machine does not have the memory parity option and
these bits are not used.
Detail information on this option is available in the manual DEC-11-HMFLA-B-D MM11-S, MF11L, and MF11-LP core memory system
Address Jumpers
Jumper Layout
Module G110 contains the address configuration jumpers for each MM11-L
board set. These jumpers are near the A B slot fingers.
