Looking at your web page:

The diagram shows 8-bit data paths and ALU, but most of the
user-registers are 16-bits.
Just curious about the architecture: at the programmer's level did it
look like a primarily 8-bit machine, or a 16-bit machine which always
processed 2 bytes in sequence, or it would best be described as mixed
8/16?
