The ROM card is also labeled with dates, updated on 4/13/93 according to the handwriting on it. This likely indicates the unit was running and updated close to the end of the Cadillac project.

Ah, great link.

Looking at the picture by Sonny Hung, NewtonOS did not make it to the prototype. The pictures look very much like a pure hardware demo, testing the pen input. Hammer is very likely not an option.

For released devices, Hemmer requires that the user installs a package on the machine first that includes the local debugger interface. I forgot about that.

I know that the ROM contains direct serial port output for debugging, but I do not remeber how to activate that.
