Unfortunately, Steve's memory allocation trick,

Geoff Collyer wrote a nice paper about experiences porting the 9th Edition
shell to SunOS 3 on the 68k some years ago.

There is a copy of source code on his personal web page:

I wonder if any of the 8th edition shell changes you mentioned survived in
that code?
