Yes definately - a very interesting machine. My first uC was a (related) 9900.

16 main registers in memory pointed to by Workspace pointer, only 3 visible
hardware registers.

I even vagely remember some instructions

BLWP (Branch - link workspace pointer)

RTWP ???

The TI MPS430 series of low power uC's has a similar intruction set...

The "all registers in memory" architecture could probably work well in a
FPGA with its high bandwidth/dual ported memory.
