I'm starting to implement the Unibus-based IO.
I know absolutely nothing about Massbus or the disk systems that were
common on the KS10. I would like to choose one disk drive type that the
KS10 supported to implement/emulate. I'm not sure which one would be
the 'best'. I'd appreciate suggestions.

The RM03 is too small to hold all of the source and do any development.
The RP06 works very nicely.
I don't think that the KS10 will boot from an RP07.
The KS10 will boot ITS from an RM80. I am not sure how well supported
it is with TOPS-10 or TOPS-20.
I would recommend the RP06 for a disk and a TU45 or TU77 for a tape.
