[cctalk] Classic computers with more than one stack pointer, but not FORTH machines.

[ben via cctalk]

Did any classic computers have a subroutine call as (S++)=PC, PC=(EFA)
as well as the standard call (--S)=PC,PC=(EFA) ?
One  could have a virtual stack machine, using helper functions without 
having to deal with return addresses on the stack.
