	I'm contemplating porting TeX to a small machine (16-bit virtual
addresses - a PDP 11/73, running RT-11 or TSX+).  Has anyone done this
particular port?  If anyone out there has ported TeX to any small machine,
or is familiar with the intermals of TeX running on a small machine, I'd
be very grateful for any information which you could share.

	My current plans are to make the large arrays RAM disk files.
(that pretty much takes care of the large data space).  I don't know
how big the code really is, but I guess it will be larger than a
16-bit virtual address can handle.  I could handle this in several ways:
multiple concurrent processes communicating through channels or shared
memory, one large process with heavily overlaid code, or several processes
that chain to each other and communicate with temporary files.

	I can't justify buying a microvax or other 32-bit machine right
now.  I know that the PDP-11 is an outdated machine, but it's what I've got.
Helpful comments would be appreciated.
