   The TI9900 might be what you remember.  It was a PDP-11 wannabe, with 16   
   registers instead of 8.  Some neat features and some weird features.

   [The registers, which TI called the workspace, were in RAM, with a   
   pointer register saying where they were.  So to stack the registers on   
   a subroutine call, you just adjusted the pointer register.  Not really   
   a stack architecture, more a predecessor to the SPARC's register
