software Z-buffer emulation

[Loki Jorgenson Rm421]

	Is there a way to emulate the capabilities of a Z-buffer 
wothout having one?  Typically, for machines without floating point
processors one has floating point software emulation.  Can one
do something similar so that one can port Z-buffer based code
directly to non-Z'd machines?

	I suspect not if I understand Z-buffers aright but I would hate
to muck about in my ignorance if it were not the case.
