Now that you have a working system, will it be used to run any specific
programs?  Based on your descriptions, the most important aspect of
the project was to get the H-11 system to run RT-11.  What I am very
curious about is what do you will do with the system now that it is running?

 >From what you have stated, both stock versions of RT-11, V04.00 and
V05.03, are being used rather than the Heath supplied versions of RT-11.
Can you please confirm this assumption?

As for the interrupt problems, using an M9047 bus grant card would
probably also have solved the problem - if you have one.

At this point, do you have any other storage other than the emulated TU58?
If so, is it a Heath product or a real DEC product and which storage is it?
