I don't think it likely.  The 5620 has a different CPU (WE32001),
much of its function in ROM, and a radically different system
organization.  An actual emulator is probably unrealizable.

One could, however, use Rob Pike's bit-map programming model
in the design of similar facilities for other bit-map displays.
I know of a couple of such efforts, but none for the 6300.
