Oh, of course!  You can do very elementary checking of a 
switch-and-lights PDP-11 with no memory, but creating any 
sort of useful program that will run using only ROM and the 
8 registers would be VERY challenging.  I suspect you might 
be able to get it to print some text on the terminal, but 
not a whole lot more. Obviously, no way to call a subroutine 
without a stack.

Well, glad you found it!
