Thanks Jay. Admittedly I'm fishing here. I know that Heath had their own RT-11 for
their floppy system but I don't have the floppy. The system is fairly generic in that
it has only the CPU, RAM and two SLUs (one of which is used for an emulated TU58). Unless
DEC made changes to the microm on the LSI-11, I think a regular distribution should work.

The OP was specifically asking about RT11 on a Heathkit H11, not "just any

Very possible I'm completely incorrect here, but I thought I recalled that
DEC gave heathkit a special price on H11 boards and OS license and such - so
that Heathkit could produce the system for a price that the home user could
actually afford back in the day. And because DEC was highly concerned that
someone would buy a card or item from Heathkit and use it in a "real DEC
PDP11" (business channel) where it would cost a lot more money normally -
they did *something* to introduce an incompatibility of some sort between an
H11 and a "real" pdp11?
