All KL10s have RH20 internal channels except the KL10-A of the
DECsystem-1080. The 1080 was intended as a drop-in replacement for a
KA10 or KI10, so the system would already have external standalone
RH10 channels.

Similarly all KL10s have cache memory except the DECSYSTEM-2040. Cache
modules could be added to the -2040 turning it into a -2050.
